The chronology

Every presidential election and, between them, every midterm, newest first, grouped into eras. Click a presidential election for the full ticket table, the electoral count and the story; a midterm row carries the House and Senate it produced.

The Polarized Era · 2016–now

Two coalitions of nearly equal size meet in a handful of swing states, and control changes hands almost every cycle: 2016 produced the fifth popular-vote/electoral-college split, 2018 the Democratic House, 2020 the highest turnout since 1900, 2022 a midterm the president's party survived, and 2024 the first Republican popular-vote win in twenty years.

The Obama Era · 2008–2014

The first African-American president, elected in the financial crisis with the largest Democratic majorities since the 1970s, then two midterms that took them away: the Tea Party wave of 2010 (the largest House swing since 1938) and the 2014 Senate loss that left him facing a Republican Congress.

The War on Terror Era · 2000–2006

The 2000 photo finish, decided by 537 votes in Florida and the Supreme Court, then an election cycle defined by September 11 and Iraq: the 2002 midterm went to the president's party, 2004 was Bush's only popular majority, and 2006 handed both chambers to the Democrats as the war soured.

The Post-Cold-War Era · 1992–1998

Perot's 19% in 1992 was the strongest third-party vote since 1912, and neither of Clinton's wins reached a popular majority. The 1994 midterm ended forty years of Democratic control of the House; 1998 was the rare midterm in which the president's party gained seats, in the middle of his impeachment.

The Long Realignment · 1968–1988

Wallace's 46 electoral votes in 1968 signalled the New Deal coalition's fracture. Nixon and then Reagan converted the South and the white working class, producing three 49-state-scale landslides in five elections, while turnout drifted steadily downward.

Cold War Consensus · 1952–1964

Eisenhower's landslides bracketed the closest election of the century in 1960, the first fought on television. The era closed with Johnson's record 61% and the Civil Rights Act, which began prying the South loose from the Democratic coalition.

The New Deal Order · 1932–1948

The Depression destroyed Republican hegemony in a single election. Roosevelt's coalition of the South, cities, labor and immigrants won four consecutive terms, redefined the federal government, and survived his death when Truman's 1948 upset confounded every poll.

Progressive Era to Normalcy · 1900–1928

Republican dominance was interrupted only when Roosevelt's 1912 third-party run split the party and let Wilson in. Women won the vote nationwide in 1920, doubling the electorate at a stroke, and the twenties produced three Republican landslides on prosperity.

The Gilded Age · 1880–1896

Two evenly matched machines fought razor-thin national elections: three of five winners in this era lost or tied the popular vote margin within a point. The Populist revolt and the realigning 1896 contest between McKinley and Bryan broke the deadlock in the Republicans' favor.

Civil War & Reconstruction · 1856–1876

The Whigs collapsed, the anti-slavery Republicans rose in a single decade, and Lincoln's 1860 victory on 39.8% of the vote triggered secession. Reconstruction elections brought Black male suffrage and ended with 1876, the most disputed election in American history.

Jacksonian Democracy · 1824–1852

Property qualifications fell, turnout among white men soared toward 80%, and the modern mass party was invented. Jackson's Democrats faced the Whigs in a stable two-party contest fought over banks, tariffs and executive power, while slavery pressed ever harder against the system's seams.

The Founding Era · 1788–1820

Washington was elected unanimously twice, then the first party system emerged: Federalists against Democratic-Republicans, a contest the Virginia dynasty won so completely that by 1820 opposition had dissolved into the Era of Good Feelings. Electors, chosen mostly by state legislatures at first, each cast two votes until the 12th Amendment separated president from vice president.

The Electoral College amplifier

The winner's share of electoral votes against their share of the popular vote since 1824. The gap between the lines is the College's exaggeration of victory, and when the lower line dips under 50% with the upper line still high, a president is being elected without a popular majority.

Congress

Presidents govern with or against Capitol Hill. Party divisions of every Congress since 1789, on the ELECTION-RESULT convention (Ashwin, 2026-10-01): a seat whose election was decided counts for its winner even where he was seated late or never (Franken in 2009, NC-9 in 2019, VA-4 in 2023, FL-1 in 2025), so a modern Senate always adds to 100; intra-term deaths and party switches are not tracked. `control` is the party that organised the chamber and `caucus` the working count per side with independents and third-party members in the caucus they sat with (a 50-50 Senate to the vice-president's party: Republican in 2001, Democratic in 2021). Audited 2026-10-01.

The midterm penalty

Since 1858 the president's party has lost House seats in 38 of 42 midterms. Changes compare seats held at the start of each Congress with two years earlier, so they can differ by a seat or two from election-night nets.

How presidential elections work

The Electoral College

Voters choose 538 electors, allocated to states by population; 270 elect the president. Every state but Maine and Nebraska awards its electors winner-take-all, which is why campaigns live in a handful of swing states.

Popular vote ≠ president

Five men have reached the White House while losing the popular count: Adams in 1824, Hayes, Harrison, Bush in 2000, and Trump in 2016. The College amplifies wins and occasionally reverses them.

If nobody gets 270

The House elects the president, one vote per state delegation. It has happened twice, in 1800 and 1824, and shaped constitutional politics both times.

The rhythm

Presidential elections every four years since 1788, the whole House and a third of the Senate every two. Midterms almost always punish the president's party, which is why trifectas rarely survive them.
