The primary election on June 5 took place under California's new blanket primary law, where all candidates appear on the same ballot, regardless of party. In the primary, voters voted for any candidate listed, or write-in any other candidate. The top two finishers — regardless of party — advanced to the general election in November, even if a candidate managed to receive a majority of the votes cast in the June primary. In the primary, less than 15% of the total 2010 census population voted. Incumbent Democratic U.S. Senator Dianne Feinstein announced her intention to run for a fourth full term in April 2011 and finished first in the blanket primary with 49.5% of the vote. The second-place finisher was Republican candidate and autism activist Elizabeth Emken, who won 12.7% of the vote.

Feinstein and Emken contested the general election on November 6, with Feinstein winning re-election in a landslide, by 62.5% to 37.5%. Feinstein's 7.86 million votes set the all-time record for the most votes cast for one candidate in one state in one election, beating Senator Barbara Boxer's 6.96 million votes in 2004.
