Incumbent Democrat Jim Costa's reelection bid in California's 21st Congressional District anchors the strong trader consensus favoring the Democratic Party. The Central Valley seat carries a D+6 partisan lean based on 2024 presidential results following mid-decade redistricting, positioning it as Likely Democratic across major forecasters. Costa maintains a substantial fundraising advantage and faces no significant Republican challengers capable of narrowing the gap ahead of the June 2 top-two primary. With multiple Democratic candidates competing but the general election on November 3 still months away, the market reflects the limited path for Republican advances in this district.
