Ami Bera (D) leads Robb Tucker (R) by roughly 16 points in the November 3, 2026 general election for California's 3rd House district, with more than 80 percent of expected votes counted and a margin consistent with the 15-20 percent band. The outcome reflects the district's post-redistricting partisan composition and Bera's established incumbency advantage in a top-two primary that advanced the two major-party nominees. Vote processing in Sacramento and surrounding counties has produced stable shares near 58 percent Democratic, aligning trader pricing on that margin range while assigning low probability to wider or narrower Democratic victories and negligible odds for a Republican win. Certification is scheduled for December, but current tallies show no material movement expected from remaining ballots.
