2010 U.S. Senate Election Results: Democratic Retained Control ✓

The 2010 U.S. Senate elections were held on November 2, 2010, alongside the midterm elections during President Barack Obama’s first term. Republicans gained six seats, significantly reducing the Democratic majority in the Senate, although Democrats retained control of the chamber with a 53–47 majority (including independents who caucused with Democrats). The elections were heavily influenced by the Tea Party movement, economic concerns following the Great Recession, and opposition to the Obama administration’s policies, including the Affordable Care Act.
