The 12 Closest Presidential Elections in American History

The presidency is decided at the margins, not in the totals

The national popular vote is a headline number. It has never once elected a president. What elects presidents is the distribution of votes across states, and this list measures exactly that. In five of the twelve elections here, the loser of the decisive contest won more total votes nationwide: Tilden in 1876, Cleveland in 1888, Gore in 2000, Clinton in 2016, and, by the House contingency standard, Jackson in 1824. The framework pays no attention to which party benefited. Both parties have won on this arithmetic and both have lost on it.

The single smallest number on the list is 537. That was Florida's certified margin in 2000 out of 5,825,043 votes cast for the two leading candidates in the state, a margin of 0.009 percent (FEC, Federal Elections 2000). The recount litigation ended at the Supreme Court on December 12, 2000, when Bush v. Gore halted the statewide manual recount (531 U.S. 98). Al Gore won the national popular vote by 543,895 votes and lost the presidency by 537 votes in one state. That is the entire logic of this ranking in a single sentence.

1876: the closest and the ugliest

By electoral margin, nothing matches 1876. Rutherford B. Hayes won 185 electoral votes to Samuel Tilden's 184, the only one-vote Electoral College decision in American history (National Archives, Electoral College results). Tilden won the popular vote 50.9 percent to 47.9 percent and went to bed needing one more electoral vote. Twenty electoral votes from Florida, Louisiana, South Carolina, and Oregon were submitted with competing certificates. Congress created a 15-member Electoral Commission, and it awarded every disputed vote to Hayes by an 8 to 7 party-line margin. Florida's returns turned on fewer than a thousand votes under any counting. The resolution came two days before inauguration, alongside the informal settlement historians call the Compromise of 1877, which ended Reconstruction. No other American election combined a closer margin with higher constitutional stakes.

New York and California: two states that were the whole game

Before the modern battleground map, single large states repeatedly decided the presidency by hair-thin margins. In 1884 Grover Cleveland carried his home state of New York by 1,047 votes out of 1,167,003 cast, and with it the White House (Library of Congress, election resource guides). Four years later the same state ran the same play in reverse: Benjamin Harrison took New York by 14,373 votes in 1888, and Cleveland became the first president to win the popular vote and lose reelection. In 1916 the game moved west. Charles Evans Hughes was widely reported the winner on election night; when California finished counting, Woodrow Wilson had carried the state by 3,773 votes, and its 13 electors reelected him 277 to 254 (Clerk of the House, election statistics, 1916).

The pattern holds in the modern era with different states. In 1976 Jimmy Carter beat Gerald Ford by 1.7 million votes nationally, yet Ohio and Hawaii together sat on an 18,489-vote combined margin; a swing of under 9,300 voters would have kept Ford in office. In 1948, the year of the Chicago Tribune's premature headline, Harry Truman's 303 electoral votes rested on a combined 58,584-vote margin in Ohio, California, and Illinois, meaning a shift of fewer than 30,000 votes would have unwound the most famous upset in American history (Truman Library).

The 21st century: three of the twelve in six elections

The Electoral College has been unusually tight in the modern era. Three of the last seven presidential elections make this list. In 2000 the margin was 537 votes. In 2016 Donald Trump lost the national popular vote by 2,868,686 but won Michigan, Wisconsin, and Pennsylvania by a combined 77,744 votes, taking all 46 of their electoral votes (FEC, Federal Elections 2016). In 2020 the same mechanism nearly ran in reverse: Joe Biden won nationally by 7,059,526 votes, 4.5 percentage points, yet his margins in Arizona, Georgia, and Wisconsin summed to just 42,918 votes. Had those three states flipped, the Electoral College would have tied 269 to 269 and the House, voting by state delegation, would have decided the presidency (FEC, Federal Elections 2020; National Archives).

If it surprises readers that a 7-million-vote landslide ranks among the closest elections ever, the surprise is the point. The decisive margin and the popular margin are different measurements, and only one of them selects presidents.

What the deadlocked elections teach

The two contingent elections on this list broke the system in ways vote counting never did. In 1800, Thomas Jefferson and his own running mate Aaron Burr each received 73 electoral votes because electors could not then distinguish presidential from vice presidential ballots. The House needed 36 ballots over six days to elect Jefferson, and the Twelfth Amendment, ratified in 1804, rewrote the mechanism (National Archives). In 1824 Andrew Jackson led in both popular and electoral votes, 99 electors to John Quincy Adams's 84, but without a majority the House chose Adams. Jackson's supporters called it the Corrupt Bargain after Henry Clay, the eliminated fourth candidate, backed Adams and became Secretary of State. Whatever one calls it, the record is plain: the candidate with the most votes did not become president, and four years later Jackson won 56 percent of the popular vote and settled the argument.

A note on near-misses. The smallest national popular vote margin in American history does not appear in the top ranks of this list, and that fact illustrates the methodology. In 1880 James Garfield beat Winfield Hancock by 1,898 votes nationwide, 0.11 percent, the thinnest national margin ever recorded (Clerk of the House, election statistics). But Garfield's electoral margin was a comfortable 214 to 155, and his decisive state, New York, went his way by more than 20,000 votes. By the ruler that actually selects presidents, 1880 was not especially close. The same logic keeps 2004 off the list: George W. Bush's reelection hinged on Ohio's 118,601-vote margin, real but wide, and his national margin of 2.4 points was the smallest ever for a reelected incumbent. Close is a question of where the votes sat, not how the total read.
