Incumbent Rep. Adam Gray (D) leads trader consensus at 71% implied probability to retain California's 13th Congressional District, buoyed by his narrow 2024 flip of the seat and fundraising edge with $1.8 million cash on hand entering the June 2 top-two primary. Recent Central Valley mayors' and local leaders' endorsements on May 7 and 11, respectively, alongside strong early mail ballot returns showing Democratic voters at 48%, have reinforced his position against challengers Daniel Garibay Rodriguez (D), Vin Kruttiventi (R), and better-funded Kevin Lincoln II (R). Forecasters like Cook Political Report rate the race Lean Democratic, citing Gray's overperformance of Kamala Harris in Merced County, though the even partisan split (Harris 48.8%, Trump 48.4%) keeps it competitive ahead of the November 3 general election.
