It was a three person race for San Luis Obispo County's District 4 Supervisor's seat, currently held by Governor Brown appointee Caren Ray.
Ray gathered 42.6 percent of the vote on Tuesday, putting her in second place.
Challenger Lynn Compton topped the vote totals with 46.43 percent.
Compton and Ray will now face off in November, because nobody got more than 50 percent.
Mike Byrd came in a distant third with 10.8 percent of the vote.
