City Councilwoman Sherri Lightner held onto the District 1 council seat on Tuesday.
Lightner defeated challenger Ray Ellis 54.18 percent to 45.82 percent with all precincts reporting early Wednesday, according to the San Diego County Registrar of Voters.
District 1 includes La Jolla, University City and much of the Carmel Valley area.
Lightner’s win will usher in a Democratic majority on the council, a dynamic that appears likely to enable Democratic Mayor-Elect Bob Filner’s agenda.
Lightner and her supporters unofficially declared the incumbent the victor at Tuesday night’s election gathering at Golden Hall.
