Imperial Beach Mayor Aguirre Wins San Diego County Supervisor Seat

Imperial Beach Mayor Paloma Aguirre has won the District 1 seat on the San Diego County Board of Supervisors, defeating Chula Vista Mayor John McCann with 53.22% of the vote. The election was held to replace former Supervisor Nora Vargas, with a voter turnout of about 19%, and most ballots were cast by mail. Aguirre campaigned on addressing the Tijuana River sewage crisis and opposing policies from the Trump administration seen as harmful to working-class communities. McCann conceded and expressed willingness to collaborate with Aguirre on regional challenges like environmental issues and public safety. Aguirre's victory will shift the Board of Supervisors to a 3-2 Democratic majority, as the board is currently split evenly between Democrats and Republicans. The election results are expected to be certified by July 31, with Aguirre set to serve the remainder of the term through January 2029.
