2010 United States elections in the context of Wave elections in the United States

The Tea Party movement was an American fiscally conservative political movement within the Republican Party that began in 2007, catapulted into the mainstream by Congressman Ron Paul's presidential campaign. The movement expanded in response to the policies of Democratic president Barack Obama and was a major factor in the 2010 wave election in which Republicans gained 63 House seats and took control of the U.S. House of Representatives.

Participants in the movement called for lower taxes and for a reduction of the national debt and federal budget deficit through decreased government spending. The movement supported small-government principles and opposed the Affordable Care Act (also known as Obamacare), President Obama's signature health care legislation. The Tea Party movement has been described as both a popular constitutional movement and as an "astroturf movement" purporting to be spontaneous and grassroots, but alleged to have been influenced by outside interests. The movement was composed of a mixture of libertarian, right-wing populist, and conservative activism. It sponsored multiple protests and supported various political candidates since 2009. The movement took its name from the December 1773 Boston Tea Party, a watershed event in the American Revolution, with some movement adherents using Revolutionary era costumes.

Joe Biden served as the 47th vice president of the United States during the presidency of Barack Obama from January 20, 2009, to January 20, 2017. Biden, a member of the Democratic Party who previously served as a senior U.S. senator representing Delaware from 1973 to 2009, was selected as Obama's running mate and took office following their victory in the 2008 presidential election over Republican nominees John McCain and Sarah Palin. Four years later, in the 2012 presidential election, they defeated Republican nominees Mitt Romney and Paul Ryan, to win re-election. Biden was the first vice president from Delaware and the first Roman Catholic vice president in U.S. history.

Alongside Biden's vice presidency, the Democratic Party also held their majorities in the House of Representatives and the Senate during the 111th U.S. Congress following the 2008 elections, attained an overall federal government trifecta. Biden was more influential than most vice presidents due to his long Senate career and relationships with both members of Congress and politicians abroad. His relationship with Republican Senate leader Mitch McConnell was particularly important after the Republicans regained control of Congress in the 2010 and 2014 elections, and the two were instrumental in ending the 2011 and 2013 debt-ceiling crises.
