# 2012 United States House of Representatives elections

The 2012 United States House of Representatives elections were held on November 6, 2012. It coincided with the reelection of President Barack Obama. Elections were held for all 435 seats representing the 50 U.S. states and also for the delegates from the District of Columbia and five major U.S. territories. The winners of this election cycle served in the 113th United States Congress. This was the first congressional election using districts drawn up based on the 2010 United States census.
Although Democratic candidates received a nationwide plurality of more than 1.4 million votes (1.1%) in the aggregated vote totals from all House elections, the Republican Party won a 33-seat advantage in seats, thus retaining its House majority by 17 seats. Democrats picked up 27 previously Republican-held seats, but most of these gains were canceled out due to Republican pick-ups of Democratic-held seats, and reapportionment gains that benefited Republicans, leaving the Democrats with a net gain of just eight seats.
This disparity — common in close elections involving single-member district (especially plurality) voting — has sometimes been attributed to targeted Republican gerrymandering in the congressional redistricting process following the 2010 United States Census. "Unintentional gerrymandering," — the high concentration of Democrats in urban centers—leading to "wasted votes" in districts that easily elected Democratic candidates, has also been cited as causing some of the efficiency gap. The GOP also benefited from having a greater number of incumbents, who tend to have an advantage in elections which may have helped Republicans win close elections for individual seats.
This marked the last of five House elections in which the party that won the popular vote was unable to receive a majority in the House. The previous four times were in 1914, 1942, 1952, and 1996; in the former two elections, Democrats won the House majority without winning the popular vote, whereas in the latter two, the Republicans did so.
As of 2025, this is the last time Democrats won a House seat in West Virginia. With the Democrats' simultaneous victories in both of New Hampshire's congressional districts, this was also the last time either party flipped control of an entire House delegation.

## California

California retained its fifty-three seats: four new seats were created when four pairs of Representatives were redistricted to run against each other. An additional Republican incumbent, Gary Miller, won re-election in an entirely different district from the one he had previously represented. The election featured the first use of the top-two primary system in which primary elections list candidates from all parties on one ballot, and the top two vote-getters advance to the general election. Two elections (30th and 44th districts) featured two Democratic incumbents running against each other.
