California's redrawn 48th Congressional District, a key battleground, could determine control of the U.S. House.
The district, gerrymandered to favor Democrats, faces a crowded primary that might backfire. - The new district would have voted for Kamala Harris by 3 points in 2024.
- A crowded Democratic field risks two Republicans advancing to the general election. - Incumbent Darrell Issa dropped out, endorsing Jim Desmond.
- The primary is June 2, with polls showing Desmond leading. The outcome hinges on local factors and candidate coordination, with national implications for House control.
