2004 United States presidential election in Louisiana

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

Louisiana was won by incumbent President George W. Bush by a 14.5 percent margin. Prior to the election, all twelve news organizations considered this a state Bush would win, or otherwise a red state. Bush's performance constituted a much wider margin than that of his 2000 results, which were 6.8 percent smaller. The state, like other states in the Deep South, is racially polarized when it comes to presidential elections, as a wide majority of the white population votes Republican, and a wide majority of the black population votes Democratic.

In this election, Louisiana voted 12.05% to the right of the nation at-large.

As of 2020, this is the last time Louisiana voted to the left of South Carolina, Georgia, Texas, or Mississippi; and the last time Louisiana voted to the right of Arkansas.
