VACAVILLE, CA (MPG) - Solano County Fourth District Supervisor John M. Vasquez announced Feb. 13 that he has made the difficult decision to withdraw from the 2026 re-election campaign in order to focus on his health while continuing to fulfill the remainder of his current term in office.

Supervisor Vasquez has been undergoing treatment following a stomach cancer diagnosis received in April 2025. Over the past several months, he has continued to serve his constituents while receiving chemotherapy. After careful consideration and consultation with his family and close supporters, Supervisor Vasquez has determined that stepping away from the campaign is in the best interest of his recovery, his constituents and the residents of Solano County.

While he will not seek re-election, Supervisor Vasquez emphasized his commitment to serving the Fourth District through the completion of his term and ensuring a smooth transition of leadership. In that spirit, Supervisor Vasquez announced his full support and endorsement of Vacaville Mayor John Carli as his preferred successor in the upcoming election.

“This decision was not an easy one, but my health must be my priority,” said Supervisor Vasquez. “I remain deeply committed to the people of the Fourth District and will continue to carry out my duties for the remainder of my term. Looking ahead, I believe Mayor John Carli is the right leader to carry this critically important work forward. He has my full confidence, endorsement, and support.”

Mayor Carli expressed appreciation for Supervisor Vasquez’s leadership and support.

“I am truly honored by Supervisor Vasquez’s endorsement and grateful for his years of service to Solano County,” said Mayor Carli. “His dedication, even during this challenging time, is inspiring. I look forward to continuing his legacy of service and working to meet the needs of our County and communities. Without a doubt, I will work hard and earn the support of the Fourth District voters.”

Supervisor Vasquez reiterated that he will remain fully engaged in county business and will continue to advocate for the residents of Vacaville, Dixon, and the northern region of Solano County throughout the remainder of his term.

Supervisor John M. Vasquez was first elected to serve as Solano County’s Fourth District Supervisor in November 2002. The Fourth District includes the cities of Vacaville and Dixon, as well as the northern portion of Solano County.
