2004 United States presidential election

The 2004 United States presidential election was the 55th quadrennial presidential election, held on Tuesday, November 2, 2004. The Republican ticket of incumbent President George W. Bush and his running mate incumbent Vice President Dick Cheney were elected to a second term, defeating the Democratic ticket of John Kerry, a United States senator from Massachusetts and his running mate John Edwards, a United States senator from North Carolina. As of 2020, this is the only presidential election since 1988 in which the Republican nominee won the popular vote (as well as the last time the Democratic nominee lost the popular vote) and the only presidential election since 1984 in which the incumbent Republican president won re-election. Due to the higher turnout, both major party nominees set records for the most popular votes received by a major party candidate for president; both men surpassed Reagan's record from 20 years earlier. At the time, Bush's 62,040,610 votes were the most received by any nominee for president, although this record would be broken four years later by Barack Obama. Bush also became the only incumbent president to win re-election after previously losing the popular vote. He was the second sitting President in a row (after Bill Clinton) to win a second term. Bush won 4 states in 2004 that have not voted Republican since: Virginia, Colorado, Nevada and New Mexico. In contrast, this is the last election that the losing candidate won any of the following states: Michigan, Pennsylvania, and Wisconsin.

Bush and Cheney were renominated by their party with no difficulty. Former Vermont governor Howard Dean emerged as the early front-runner in the 2004 Democratic Party presidential primaries, but Kerry won the first set of primaries in January and clinched his party's nomination in March after a series of primary victories. Kerry chose Edwards, who had himself sought the party's 2004 presidential nomination, to be his running mate.

Bush's popularity had soared early in his first term after the September 11 attacks in 2001, but it had declined significantly by 2004. Foreign policy was the dominant theme throughout the election campaign, particularly Bush's handling of the war on terror and the 2003 invasion of Iraq. Bush presented himself as a decisive leader and attacked Kerry as a "flip-flopper". Kerry criticized Bush's conduct of the Iraq War, despite having voted for it himself. Domestic issues were debated as well, including the economy and jobs, health care, abortion, same-sex marriage and embryonic stem cell research.

Bush won by a narrow margin of 35 electoral votes and took 50.7% of the popular vote. Bush swept the South and the Mountain States and took the crucial swing states of Ohio, Iowa, and New Mexico, the latter two flipping Republican. Although Kerry flipped New Hampshire, Bush won both more electoral votes and states than in 2000. Ohio was the tipping-point state, and was considered to be the state that allowed Bush to win re-election. This was the first presidential election since 1988 in which a candidate received over 50% of the vote. Some aspects of the election process were subject to controversy, but not to the degree seen in the 2000 presidential election. Bush won Florida by a five-percent margin, a significant improvement over his razor-thin victory margin in the state 4 years earlier which led to a legal challenge in Bush v. Gore.
