2008 U.S. Senate Election Results: Democrats Retained Control ✓

The 2008 U.S. Senate elections were held on November 4, 2008, alongside the presidential election. Democrats had a strong year, gaining eight seats and expanding their majority in the Senate, aided by high turnout and the Democratic wave that accompanied Barack Obama’s presidential victory. Following the elections and subsequent party switches, Democrats held a large majority and briefly reached a 60-seat, filibuster-proof majority in 2009.
