Tuesday is the deadline to cast ballots in the special election to fill the District 1 seat on the San Diego County Board of Supervisors necessitated by Nora Vargas’ late-December announcement that she would not serve her second term, despite winning re-election in November.
Chula Vista Mayor John McCann topped the field of seven candidates in the April 8 primary, drawing 43.58% of the vote. Imperial Beach Mayor Paloma Aguirre earned the other spot in the runoff by finishing second with 31.62%.
District 1 consists of three cities — Chula Vista, Imperial Beach and National City — 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.
The current makeup is split between two Democrats — Terra Lawson-Remer and Monica Montgomery Steppe — and two Republicans, Joel Anderson and Jim Desmond.
Aguirre told City News Service she is “running to bring change to county government, to fight on the side of working people and start getting results we all need — fixing the sewage crisis, lowering energy rates and fighting crime in every community.”
Born in San Francisco, Aguirre has called Southern California home since 2001 and has been Imperial Beach’s mayor since December 2022.
She has been outspoken on the U.S.-Mexico border sewage pollution problem, which has led to closed beaches, along with causing serious health issues for some residents.
Aguirre said she’ll “get the county off the sidelines” by funding infrastructure, demanding Superfund designation from the Environmental Protection Agency and “treating this as the public health emergency it is.”
Had a great visit with the firefighters at the Otay Mesa station — the everyday heroes who protect our families and neighborhoods. I’m proud to be endorsed by our County Firefighters and stand with the men and women who always show up when we need them most. ?? #IAFF2881 pic.twitter.com/0yERFzTbfP
— Paloma Aguirre (she/her/ella) (@paloma4D1) July 1, 2025McCann, a Navy veteran and Chula Vista native first elected as that city’s mayor in 2022, said on his website that Chula Vista’s wildfire response has “demonstrated his ability to protect residents in times of crisis.”
McCann’s platform includes increased funding for law enforcement, and “fighting to lower the cost of living by cutting government waste, opposing unnecessary tax hikes, and blocking burdensome policies like the mileage tax and (San Diego Association of Governments) tax.”
In response to the border sewage problem, McCann said he has “been actively working with local, state and federal officials to secure funding for infrastructure improvements, hold responsible parties accountable and push for long-term solutions to stop the flow of toxic waste into our waters.”
