2004 United States presidential election in Michigan

The 2004 United States presidential election in Michigan took place on November 2, 2004, and was part of the 2004 United States presidential election. Voters chose 17 representatives, or electors to the Electoral College, who voted for president and vice president.

Michigan was won by Democratic nominee John Kerry by a 3.4% margin of victory. Although no Republican carried this state in a presidential election since Bush's father George H. W. Bush in 1988, early polling showed the race was a toss-up, thus was considered as a possible target for the Republicans. Later polling favored Kerry, leading half of the news organizations to predict that Kerry would win the state, but the other half still considered it a swing state.

Although Michigan was also not carried by the winner of the 2000 presidential race, 2004 also marked the first time since 1976 in which the state was not carried by the candidate who led in the overall popular vote. Bush was the first Republican to win the popular vote without Michigan since the 1968 presidential race. Bush is to date the only Republican presidential candidate to win two terms in office without winning Michigan at least once, as well as the most recent Republican to win without the state. This marked the only the second time since Franklin Roosevelt defeated Herbert Hoover in 1932 that an incumbent president would win reelection without carrying Michigan in the election cycle in question.

As of 2020, this is the most recent election in which Michigan would vote for the losing candidate, thus the state is tied with Wisconsin and Pennsylvania for the longest bellwether streak in the nation.
