Incumbent Adam Gray (D) and Kevin Lincoln II (R) are running in the general election for California's 13th Congressional District on November 3, 2026.
FOX26's Liz Gonzalez said, "The 13th Congressional District has been among the most closely watched races across the nation in recent elections—and this year likely won’t be any different. While the district has historically leaned Democrat, that doesn’t always guarantee a clear pathway." In 2024, Gray defeated then-incumbent John Duarte (R) by 187 votes out of more than 210,000 cast. As of July 2026, major election forecasters rated the general election Lean Democratic or Tilt Democratic.
The election is taking place in the context of redistricting that changed the district lines from those used in 2024. Inside Elections' Nathaniel Rakich said, "The proposal adds the city of Stockton to the district, pushing it from an evenly divided Baseline to D+6. However, as Latino voters have shifted right in recent years, this district has gotten better for Republicans."
