SACRAMENTO, Calif. (AP) – The California Democratic Party and labor unions say they won’t back down any time soon after their candidate lost a costly state Senate race in the San Francisco Bay Area.

Orinda Mayor Steve Glazer, a business-backed moderate, defeated fellow Democratic Assemblywoman Susan Bonilla by a significant margin in a special election this week. Party officials and union leaders blamed higher Republican turnout for their loss and vowed to fight again.

Glazer said Wednesday that he remains committed to the party and is looking forward to building relationships with both Democrats and Republicans in the Senate.

Senate President Pro Tem Kevin de Leon says he reached out to welcome Glazer as a colleague. The Los Angeles Democrat did not endorse either candidate.

Glazer replaces Mark DeSaulnier, who was elected to Congress.
