United States
The world's most consequential political system is running a live experiment on itself: how much can be governed by decree, and which of the brakes still grip.
(73% among Republicans, down from 86% in January; 4% among Democrats)
(duties collected were 6.7% of import value in July 2026, after the Supreme Court struck the emergency tariffs down)
(with about 10 million more people projected uninsured by 2034)
A note on framing. The United States appears on more pages of this site than any other country, and on every one of them it is somebody else's variable: the issuer of the dollar, the anchor of the postwar order, the other half of the China rivalry. This page treats it as the subject, in the middle of the most contested political experiment the country has run on itself since the 1930s. One rule governs what follows. Where an action has an actor, the actor is named. A page that says institutions "have been challenged" without saying by whom is not being neutral; it is being evasive. Naming is not verdict-passing. Both partisan readings of this presidency appear below in their strongest forms, and the reader keeps the job of choosing between them.
Where things stand
Twenty months into Donald Trump's second term, the experiment in the subtitle has a preliminary reading. The question being tested is not left against right. It is how much of a constitutional system's daily operation can be moved into one office between elections - and which of the old brakes still grip when that happens. As of September 2026 the answer to both halves is: more than expected. The presidency has governed largely by decree - in its own account, to make a permanent government answer to an elected one. The courts, the states, the bond market and, in November 2025, the voters have all objected - unevenly, slowly, and often effectively.
What makes the moment hard to read is that it has no single genre. Watergate was a scandal, 2008 was a crash, the 1950s red scare was a panic; 2025-26 is upheaval and normality running concurrently. Groceries get bought, flights land, a World Cup came and went - while the machinery of the state is stress-tested harder than at any point in living memory. A chronicle collapses under that kind of split screen, so this page is built from mechanisms instead: how the power was assembled, what it has been spent on, what has pushed back, and what is fracturing. Start with the assembly.
How he returned
Donald Trump's 2024 win needs no conspiracy and no miracle to explain. It needs three ordinary mechanisms, stacked. First, the global anti-incumbent wave. 2024 was the worst year for governing parties across the developed world in the modern polling era: electorates punished whoever presided over the post-pandemic inflation, and the United Kingdom, Japan and a dozen other incumbents took the same hit. Second, a coalition shift a decade in the making. The Republican vote became less white, less college-educated and more working-class, while the Democratic coalition concentrated among graduates. The parties partly swapped class positions, and the swap favored the side whose voters are spread more efficiently across states. Third, the prosecutions meant to disqualify him did the opposite for his own electorate. Each indictment consolidated the primary, funded the campaign, and fed the story that the system itself was the opponent; a felony conviction in New York moved almost no votes. That is what this site's trust pages would predict: where institutional trust has collapsed, institutional condemnation stops transferring.
Worth stating because it is often skipped: the win was real and unambiguous - all seven swing states and, unlike 2016, the popular vote. Whatever else this page describes, voters chose it, with full knowledge of January 6th and the felony record. Roughly half the voters chose a disruptor knowing he was one. Any account of what follows that leaves out the demand for it is missing half the story.
Government by emergency
The signature method of the second term is not any single policy. It is the systematic use of emergency and unilateral authority to do what previously required Congress. The clearest case is the tariff program. From February 2025 the administration imposed tariffs, near-universal by April, by invoking the International Emergency Economic Powers Act - a 1977 statute written for sanctions, never before used by any president for tariffs. It cited emergencies over fentanyl and over trade deficits that, it said, had "led to the hollowing out" of American manufacturing. For nearly a year, the largest peacetime trade-policy shift in ninety years ran on a contested reading of that law. The average effective rate, 2.4% in January 2025, briefly touched 28% that April and settled near 18% by the autumn - by the Yale Budget Lab's count, the highest since the 1930s. The same pattern repeated across the government. National emergencies were declared at the border and in energy policy. Inspectors general were dismissed en masse, spending was withheld from programs Congress had funded, and the federal civilian workforce outside the Postal Service shrank by 14%, about 330,000 jobs, between January 2025 and August 2026. The Department of Government Efficiency - the Musk-led cost-cutting unit that operated through most of 2025 with contested legal status before being wound down - rewrote agencies from inside.
The method has a logic that outlasts any one administration. With congressional majorities too thin to legislate much, decree is the path of least resistance, and each emergency statute is a key someone previously left in the lock. What the method met, eventually, was the judiciary. On February 20, 2026 the Supreme Court ruled 6-3 that the emergency-powers act does not authorize tariffs at all; Chief Justice Roberts wrote the opinion, joined by two of the three justices Trump appointed. The administration answered within days with narrower statutes. A temporary 10% tariff ran its legal maximum of 150 days, to July 24; tariffs of 10-12.5% on 60 economies, framed as pressure to ban imports made with forced labor, replaced it. The sector tariffs on metals, autos and copper - and the separate China tariffs - survive. By mid-September customs officials had certified about $122 billion in refunds, with interest, of some $166 billion collected under the voided theory. The episode is the term in miniature. Sweeping unilateral action, a long unconstrained run, a partial judicial reversal - and a residue still far larger than the status quo ante.
The economy, holding its breath
The 2024 mandate was, at bottom, "bring prices down." Two years in, the price level is the administration's weakest ground. Inflation re-accelerated through the first half of 2026, peaking above 4% by the Federal Reserve's preferred measure in May and easing to 3.7% in July - nearly double the target. Unemployment stands at 4.1%, growth ran at a 1.5% annual rate in the second quarter, and consumer sentiment is at recession-grade levels. It is the combination for which the word stagflation keeps being reached. How much of the inflation is oil, tariffs, or fiscal and monetary policy is contested; the disagreement section below leaves it contested. The fiscal arithmetic is not. The One Big Beautiful Bill Act of July 2025 was the term's main legislative achievement, in a Congress that legislated little else. It extended the 2017 tax cuts, financed the enforcement build-up described below, and added a projected $3.4 trillion to ten-year deficits. The deficit for the first eleven months of fiscal 2026 was $1.97 trillion, level with a year earlier; net interest passed $1 trillion, more than defense, on a total debt of $40.1 trillion.
The monetary institutions took the stress test directly. The president spent 2025 demanding rate cuts and attempted to fire Federal Reserve governor Lisa Cook. The courts blocked the firing, and in June 2026 the Supreme Court kept her in office, 5-4, rejecting a reading that would make governors removable at will - one of the term's most consequential institutional holds. When Jerome Powell's term as chair ended, the replacement was Kevin Warsh, confirmed 54-45 in May 2026: the narrowest and most partisan confirmation a Fed chair has ever received. In September the Fed under Warsh raised rates, 12-0, to 3.75-4%, saying inflation "remains elevated." The market constraint has proved stickier than the political one. Each episode of maximum tariff or Fed pressure in 2025 was followed by a bond-market wobble and a partial retreat - a rhythm traders named early and governments noticed. The ten-year Treasury yield hit a 2026 high of 5.18% on September 24. A presidency that has tested most domestic checks still watches the Treasury auction.
The stress test: what bent, what held
What bent. The Justice Department's independence from the White House - a post-Watergate norm rather than a law - ended as a working fact, its critics say; the administration says it ended a "weaponization" of law enforcement against the president and his supporters, as a first-day executive order put it. The president publicly directed prosecutions of named adversaries, and indictments duly followed against former FBI director James Comey and New York attorney general Letitia James. Both were dismissed in November 2025 because the prosecutor installed to bring them had been unlawfully appointed - an exit on process grounds that left the substance unresolved. Since June 2026 about 8,000 senior posts, placed in a new category called Schedule Policy/Career, have been removable at will - accountability, the government says; a breach of civil service law, say the unions and employee groups suing over it. Regulatory leverage was turned on broadcasters and universities: the comedian Jimmy Kimmel was taken off air for a week under Federal Communications Commission pressure after the Kirk assassination, and networks and Ivy League schools paid settlements. The Pentagon was rebranded the Department of War. The Varieties of Democracy (V-Dem) project recorded the sharpest one-year fall in its US series; the fuller measurement dispute is covered on the democracy page.
What held. The courts held first, including a Supreme Court one-third appointed by the president. It voided the tariff theory, kept the Fed governor in office and struck down the order denying citizenship to US-born children of parents present illegally or temporarily. In December 2025 it refused, 6-3, to let the National Guard deploy in Illinois, and the troops were then withdrawn from Chicago, Los Angeles and Portland. The same Court also widened presidential power, backing the administration in a run of emergency appeals and, in June 2026, letting it fire Federal Trade Commission members at will, overruling a 1935 precedent. Elections continued to run and to move power away from the incumbent party. Democrats swept the November 2025 state races and lead the polls for the midterms. Federalism held: governors and state courts blocked deployments and data demands. Congress, which has passed few major laws, found one working tool in the purse. A 43-day full shutdown in late 2025 was followed by a targeted 2026 one that defunded the Department of Homeland Security alone for two and a half months. And the streets stayed full and largely peaceful. The third "No Kings" day, in March 2026, drew at least 8 million people by its organizers' estimate; the White House said they were driven by "leftist funding networks." None of the rounds produced the civil violence both political extremes had priced in.
One more ledger entry belongs here, because it moved from tail-risk to recurring: political violence. The former speaker of the Minnesota house and her husband were assassinated in June 2025. Charlie Kirk, founder of the conservative youth group Turning Point USA, was assassinated that September. National Guard soldiers were shot near the White House in November; federal agents killed two US citizens during immigration operations in Minneapolis in January 2026. Each side's violence is the other side's proof text, which is precisely how the mechanism sustains itself.
Force at home
The enforcement build-out is the term's largest physical fact. The One Big Beautiful Bill directed roughly $170 billion toward immigration enforcement, making Immigration and Customs Enforcement (ICE) the best-funded federal law-enforcement agency. National Guard units were ordered into Los Angeles, Washington, Memphis, Chicago and Portland, often over the objections of the states and cities involved. The administration's case starts at the border, where it reports daily encounters down 95% from the Biden years. The removal numbers deserve this site's usual hygiene. ICE recorded about 320,000 removals in fiscal 2025 and 356,000 in fiscal 2026 by mid-July - a pace that would pass the record of about 410,000 set under Obama in fiscal 2012. The administration's headline claims run far larger - more than 675,000 deportations and an estimated 2.2 million "self-deportations" in its first year - but they fold in border returns and figures independent analysts cannot verify. Removals and departures both rose; the larger change is in the manner. Masked agents, third-country transfers, and enforcement at schools and in hospital wards - venues that previous administrations of both parties had largely treated as off-limits.
The manner is what generated the backlash. Federal immigration officers shot fourteen people between September 2025 and February 2026. In January federal agents killed two US citizens in Minneapolis: Renee Good, shot by an ICE officer as she turned her car away, and Alex Pretti, a nurse filming an operation, shot by border officers who had pinned him down and taken a handgun from his waist. Officials said Good had run over an officer and that Pretti came to "kill law enforcement"; videos verified by news organizations contradicted both accounts. The killings led Senate Democrats to block the homeland-security funding bill, hence the agency shutdown. Support for mass deportation, majority-level in 2024 polling, inverted as the abstraction became footage. In June 2026, 58% opposed deporting everyone in the country illegally and 73% called immigration good for the country, below 2025's record 79% (Gallup). The pattern is one this site's pages keep finding: policies win as symbols and lose as scenes.
The coalition and its fractures
From outside, the most analytically interesting American story of 2025-26 is not the president against his opponents. It is the president against his own coalition, because that fight exposes what the coalition is made of. The movement traveling under the Make America Great Again banner (MAGA) was always a federation of factions: restrictionists, evangelicals, the tech right, anti-war populists, class-realignment converts. What held it together was not a program but a person, plus a shared media economy whose stars own their audiences the way the party once owned its voters. That ownership structure is the mechanism to watch. When loyalty to the leader and loyalty to the audience diverge, the audience wins, because the audience is the asset.
Three fractures tested it. Elon Musk, the campaign's largest donor and briefly the government's in-house cost-cutter, broke publicly in June 2025 over the deficit arithmetic of the One Big Beautiful Bill. He threatened a third party; the president threatened his companies' federal contracts. By 2026 the alliance was patched at the level of interests: Musk traveled with the president to Beijing in May, and his political action committee is spending to keep Congress Republican. The Epstein files cut deeper, because the wound was internal. The administration's July 2025 decision to close the matter contradicted years of its own allies' promises and produced the first real base revolt of the term. Congress forced release almost unanimously in November 2025. Inside the coalition, the fight cost the president his most loyal congressional ally: Marjorie Taylor Greene, branded a traitor by Trump, resigned her seat in January 2026. The Iran war then broke the anti-interventionists. Tucker Carlson, the movement's most-watched voice, said the February 2026 strikes abandoned "America First." By June he saw "no chance" of backing Republicans in the midterms; on July 1 he said he would help build a third party, and he has hosted Greene and Representative Thomas Massie at his compound in Maine.
Read the three together and the finding is double-edged. None of the defections changed a policy: the bill passed, the files moved only when Congress moved, the wars proceeded. A coalition without a program has no lever for internal dissent except exit. But every defector kept their audience on the way out, and that is the problem the next Republican nominee inherits. The coalition has so far transferred only weakly by endorsement, and its factions are already auditioning successors. Its founder turns eighty-two before the next inauguration, having alternately floated and disclaimed a constitutionally barred third term. Personalist movements are at their most unpredictable not in power but at succession. This one has scheduled its succession problem for 2028.
Abroad, briefly
Other pages own the detail: the Iran war on the Middle East page, the stalled peace track on the Ukraine and Russia pages, the alliance strain on the postwar-order page. Here, only the through-line. The doctrine, insofar as one exists, is spheres of influence, enforced transactionally. Iran got a war that killed its supreme leader, then a truce that collapsed, a naval blockade and, by late September, no settlement. Venezuela got the January 2026 capture of Nicolás Maduro by special forces in Caracas, followed by a US-backed interim government under his deputy, Delcy Rodríguez - the first foreign leader the United States has removed by force since Iraq. Ukraine got a peace track run through personal envoys; 2026 brought two short truces and no settlement, stuck on Donetsk. Allies got tariffs and territorial pressure over Greenland and Canada; for the first time since 1945, hedging against America is formal policy in allied capitals. The pattern reads less like isolationism than like empire on a budget. Fewer commitments, harder enforcement inside the claimed sphere - and a bill presented to everyone under the security umbrella.
The paths from here
Dated September 2026, with the November 3 midterms under six weeks away and the government funded only to December 11. That is itself the point: the next system tests are on the calendar.
Divided government, contested count
Democrats convert their polling lead into the House despite the mid-decade redistricting wars; investigations and impeachment votes resume; the administration governs even more by decree. The sharper variable is not who wins but whether the loser accepts the count - both parties have now built infrastructure for not accepting it.
Will it happen? The House flip is the current base case: Democrats led September's Reuters/Ipsos generic ballot by eight points among registered voters. But the redistricting arms race and an April Supreme Court ruling narrowing the Voting Rights Act's demands on district maps make seat math unusually uncertain for a wave year. Acceptance of the result is the open question. In August the Court let an election order proceed pending appeal: federal citizenship lists meant to bolster confidence in elections, which the suing states call an intrusion on their power.
The economic bill arrives
Oil, tariff pass-through, deficit-financed tax cuts and a Fed under political pressure keep inflation near 4% into 2027; the bond market, not the opposition, forces the retreat. Refunds of the voided tariffs, about $122 billion certified by mid-September, widen the deficit on the way down.
Will it happen? The ingredients are present - inflation near double the target, slow growth, rising inflation expectations. Against it, the Fed under a chair confirmed on party lines raised rates in September instead of cutting them. Watch the long end of the Treasury curve; it has been the referee this administration most consistently heeds.
The ratchet
The emergency toolkit - impoundment, Schedule Policy/Career, Guard deployments, regulatory pressure - is not returned but inherited. A future president of either party keeps the expanded keys, citing precedent, and the second Trump term is remembered less for its policies than for resetting what a president may do between elections.
Will it happen? Partially, almost regardless of who wins next: no modern executive has voluntarily returned emergency powers, and the incentive to keep them is bipartisan. The court rulings of 2025-26 narrowed specific instruments without touching the underlying statutes Congress has declined to repair. The June ruling on the Federal Trade Commission went the other way: every future president may fire such commissioners at will.
Succession without a mechanism
The coalition's factions contest 2028 without an agreed way to transfer a personal following. They include Vice President Vance as the institutional heir, the media wing now outside the party, and the tech right. A serious third-party bid from the Carlson wing, or a primary fought over who owns the base, does what redistricting and demographics could not: it splits the movement.
Will it happen? Some version is close to unavoidable. The open variables are whether the founder anoints anyone, whether an endorsement transfers - the evidence so far says weakly - and whether the third-party talk survives ballot-access law and a winner-take-all system in which no third-party presidential candidate has finished better than third since 1912.
Absorption
The system metabolizes the shock as it has before. Courts keep narrowing the instruments, elections keep transferring power, and a successor pares back the enforcement build-out. The years 2025-26 enter the textbooks as a stress test passed - expensively, but passed.
Will it happen? It is the American historical prior - the republic has absorbed Palmer raids, internment, McCarthy and Watergate - and the 2025-26 record shows more institutional resistance than the pessimist reading predicted. The reason for doubt is that every previous absorption ran through parties that accepted losing, which is the exact variable now in question.
Where serious analysts disagree
Whether this is consolidation or weakness. One reading - the political scientist Steven Levitsky's, among others - holds that the United States is now a competitive authoritarian system in formation: elections continue, but the state's machinery is being turned on opponents, and each cycle starts from less neutral ground. A second points at the record above: the courts struck the signature policies, the president's party lost the major races of November 2025, his approval fell to 32% in September, and his coalition is shedding founders - loud is not the same as strong. The administration's supporters see the Constitution working: an elected president taking charge of an executive branch that answers to him, as the Court's removal ruling partly affirmed, with judges and voters free to push back. All three fit the events. The test that separates them is scheduled: whether November 2026 runs normally and its result is accepted by both parties.
What is driving the inflation. The energy reading points to oil: Brent crude averaged over $100 a barrel from March to May as the Iran war restricted Hormuz, and inflation peaked in May - a shock that should fade. The tariff reading notes that importers pay the tax by definition and that core inflation, excluding food and energy, was still 3.3% in July. The fiscal-monetary reading answers that a $3.4 trillion deficit add plus visible political pressure on the central bank is exactly the recipe that unanchors expectations, tariffs or none; year-ahead expectations reached 4.6% in September. Each implies a different cure - patience, trade retreat, or credibility the current Fed arrangement makes harder to buy - which is why the dispute is not academic.
Whether the coalition fracture is real. Skeptics note that MAGA crack-ups have been predicted continuously since 2015 and that the movement's voters have moved far less than its elites: most Republicans still approve of the president. The feuds, on this view, are elite theater over a base that remains a bloc. The counter-evidence is behavioral rather than rhetorical: a resignation from Congress, a formal party exit, third-party organizing, money withheld and returned - and Republican approval down from 86% to 73% since January. Elite defection with a mostly stable base is exactly what the early stage of coalition decomposition looks like - and also exactly what durable movements survive. The 2028 cycle will adjudicate.
What to watch
Strip the noise and two curves carry most of the information. The first is judicial compliance: through September 2026 the administration has lost repeatedly in court and has, in the main, complied - slowly and partially, but complied, as the tariff refunds show. The day that stops being true, this page's subject changes category. The second is the November count: not who wins, but whether the machinery of certification, concession and transfer runs on rails in both directions. Everything else on this page - the tariffs, the deployments, the fractures - matters less than whether those two curves hold, because they are the difference between a rough passage inside a constitutional system and the exit from one. As of September 2026, both curves are holding, both are under visible strain, and the fairest reading is that the American system is neither fine nor finished - it is being tested in public, at full weight, with the results posted quarterly.
