Redistricting under Proposition 50 has shifted California's 3rd Congressional District toward a Democratic lean by incorporating more of northern Sacramento County, prompting incumbent Kevin Kiley to seek another seat. Democratic Representative Ami Bera, previously representing the neighboring 6th District, filed to run here and holds a significant edge in fundraising and name recognition against fellow Democrats Chris Bennett, Heidi Hall, and Lyndon Cervantes. On the Republican side, Christine Bish and Robb Tucker lead a smaller field ahead of the June 2 nonpartisan top-two primary. No major party endorsement has unified Democratic voters, leaving the outcome dependent on turnout among the district's registered voters in the final weeks before ballots are cast.
