Review note: Sarah Chapman's own campaign site (sarahchapmanformayor.com), "Dr. Sarah Chapman for Vacaville Mayor 2026": her biography (sitting Vice Mayor, Vacaville resident of nearly five decades, 28-plus years in education, past Solano Community College governing-board member) and platform (neighborhood-safety partnerships, family/youth services) in her own words, plus three named endorsements may have more bias because it is an advocacy voter guide compared to other formal government and nonprofit journalism sources.

City of Vacaville
Mayor of Vacaville
Vacaville's Mayor presides over City Council meetings. The Mayor represents the city publicly. The Mayor votes alongside six district council members on the budget and city laws. Voters elect the Mayor citywide, to a four-year term. This dataset could not confirm the city's form of government or any term limits.
Mayor John Carli did not file for reelection. The seat is open. Two candidates qualified. They are Sarah Chapman and Roy Stockton. Chapman sits on the City Council now. The top vote getter on November 3 wins. There is no runoff.
Vacaville's Mayor runs City Council meetings and represents the city in public. The Mayor votes with the city's six district councilmembers. Those votes cover the budget, ordinances, and land use. The Mayor is elected citywide, not by district. The term is four years. This November's ballot also includes three of the six council districts, 2, 4, and 6. Those are the half whose elections fall in governor election years. Districts 1, 3, and 5 fall in presidential years instead. They are not up this November. Vacaville is a Solano County city of roughly 102,400 people. The 2020 Census counted 102,386. Two things could not be confirmed here. One is the city's form of government, such as whether an appointed city manager runs daily operations. The other is any term limit rule for either office. The City of Vacaville's own site blocked every automated fetch attempt.
The county's own Candidate Filed Log marks this contest ON THE BALLOT. It is not an uncontested appointment. Both candidates qualified before the regular nomination deadline. Chapman filed July 27, 2026. Stockton filed July 31, 2026. The race is settled and genuinely contested.
Sarah Chapman
Sarah Chapman sits on the Vacaville City Council. She is also the city's Vice Mayor. She is running for the open Mayor's seat. Her campaign focuses on neighborhood safety partnerships. It also focuses on services for families and youth. She has lived in Vacaville for nearly five decades. She has worked as an educator for more than 28 years.
Roy Stockton
Roy Stockton is running for the open Mayor's seat. Their ballot designation reads "Councilmember / Sheriff's Sergeant." County records do not list them as holding that office. No independent news profile was found for them. No campaign website or civic record was found either.
Your pick
A nonpartisan office: candidates do not run as Democrats or Republicans, and no party appears on the ballot.
