Nancy Pelosi Democratic Nancy Pelosi Democratic The 2008 United States House of Representatives elections were held on November 4, 2008, to elect members to the United States House of Representatives to serve in the 111th United States Congress from January 3, 2009, until January 3, 2011.

The Democratic Party, which won a majority of seats in the 2006 election, expanded its control in 2008.

With one exception (Louisiana's 2nd district), the only seats to switch from Democratic to Republican had been Republican-held prior to the 2006 elections.

[2][3] The 10.6% popular vote advantage by the Democrats was the largest by either party since 1982, 26 years earlier, and as of 2024 remains the most recent time that either party won by a double-digit margin in the overall popular vote for the House of Representatives.

It is also the most recent, and only time since 1988 that the incumbent president's party lost house seats in a presidential election year.

As of 2024[update], this remains the last election in which Democrats won House seats in Idaho, North Dakota, and South Dakota; the last election in which Democrats won more than one seat in Alabama until 2024; and the last election in which Democrats won a majority of seats in Arkansas, Indiana, Mississippi, Ohio, Tennessee, West Virginia, and Wisconsin.

Fourteen Republicans and five Democrats lost their general elections, thereby losing their seats to the other party.
