Unofficial results released Tuesday by the Contra Costa County Registrar's Office showed Richmond Councilmember Claudia Jimenez with 17,446 votes (55.24%) to 14,137 for Ahmad Anderson, a margin the East Bay Times described as making it all but certain she will become the city's next mayor. The results have not been certified.

Jimenez, who has served on the City Council for six years, had already declared victory on her campaign website days earlier. "I am very happy to hear that I've gotten the most votes ever in Richmond," she told Bay Area News Group. "The difference is big enough to feel that it's a mandate."

Jimenez and Anderson were the top two finishers in the June primary after Mayor Eduardo Martinez lost his bid for reelection. Jimenez helped secure a $550 million settlement from the Chevron Richmond Refinery. She told the newspaper she wants to talk with residents about making the city more sustainable and about how to invest the settlement, including on deferred maintenance of city facilities.
