2010 United States elections

Elections were held in the United States on November 2, 2010, in the middle of Democratic President Barack Obama's first term. Republicans ended unified Democratic control of Congress and the presidency by winning a majority in the House of Representatives and gained seats in the Senate despite Democrats holding Senate control.

Republicans gained seven seats in the Senate (including a special election held in January 2010) but failed to gain a majority in the chamber. In the House of Representatives, Republicans won a net gain of 63 seats, the largest shift in seats since the 1948 elections. In state elections, Republicans won a net gain of six gubernatorial seats and flipped control of twenty state legislative chambers, giving them a substantial advantage in the redistricting that occurred following the 2010 United States census. The election was widely characterized as a "Republican wave" election, and President Obama called it "a shellacking."

The heavy Democratic losses in 2010 were mainly attributed to the passing of the Affordable Care Act along with a poor economic recovery from the Great Recession and large budget deficits. This marked the first election since 1858 that yielded a Republican-controlled House and a Democratic-controlled Senate.

Issues

Candidates and voters in 2010 focused on national economic conditions and the economic policies of the Obama administration and congressional Democrats. Attention was paid to public anger over the Wall Street bailout signed into law by President George W. Bush in late 2008. Voters were also motivated for and against the sweeping reforms of the health care system enacted by Democrats in 2010, as well as concerns over tax rates and record deficits.
