Kevin Kiley, the incumbent who switched districts and party registration to independent following redistricting under Proposition 50, leads early returns in California's June 2 top-two primary for the 6th congressional district. A crowded Democratic field that included Richard Pan, Lauren Babb Tomlinson, Thien Ho, Martha Guerrero, and Tyler Vandenberg has split support, allowing Republican Michael Stansfield to place second in initial counts despite limited campaign resources. Thousands of mail ballots remain outstanding, and later-counted votes in the Sacramento-area district have historically favored Democrats, leaving final advancement to the November general election unresolved. The nonpartisan primary format advances the two highest vote-getters regardless of party.
