Also on the ballot here, with nothing counted in this county yet: California Board of Equalization District 1, California Board of Equalization District 3, California Board of Equalization District 4. Counts come from each race’s official source, named on its own page. Margins are the leading two candidates’ difference in points of all votes counted. 2024 is the presidential vote, Harris against Trump, on the same ground (for a House district, the county’s part of it). A county is not compared with 2024 until a quarter of its 2024 vote is counted. Ranks are among the state’s counties with votes counted in the same race.
