Chula Vista Mayor John McCann has conceded the race for the San Diego County Board of Supervisors District 1 seat to Imperial Beach Mayor Paloma Aguirre.
He did so during a live interview on San Diego's Morning News Wednesday morning.
According to the San Diego County Registrar of Voters, as of 5 a.m. Wednesday, Aguirre led McCann 53.22% to 46.79% (37,324 votes to 32,805 votes).
The Registrar of Voters noted about 9.500 ballots were still considered outstanding. Updated results were expected to be released by 6 p.m. Wednesday.
District 1 consists of three cities -- Chula Vista, Imperial Beach and National City -- plus 15 neighborhoods in San Diego, including East Village, Mountain View and San Ysidro, and six unincorporated communities, including Bonita, East Otay Mesa and a portion of Spring Valley.
Aguirre is a Democrat and McCann is a Republican. The Board of Supervisors is technically a nonpartisan governing body, like all local government boards in California.
Entering Tuesday's election, the makeup of the board was split between two Democrats -- Terra Lawson-Remer and Monica Montgomery Steppe -- and two Republicans, Joel Anderson and Jim Desmond.
