Mayor of Windsor

Windsor's Mayor is directly elected, at-large. The Mayor presides over Town Council meetings and represents the town. The Mayor votes alongside four district council members on the budget and land use. Since 2020, voters have elected the Mayor directly. Before that, the Council chose the Mayor. The Mayor's term is two years, shorter than a district council member's four-year term.

Two people are running for Mayor of Windsor. They are Tanya Potter and Rick Massell. Potter is the Vice Mayor and the District 4 councilmember. Massell is a retired educator. The top vote getter on November 3 wins. There is no runoff.

Windsor's Mayor is directly elected at-large to a two-year term. The town's four district Council seats serve four-year terms. This is a relatively new arrangement. The Mayor's seat became a separately elected office with the November 2020 election. Before that, the Council chose the Mayor from among its own district members. Neighboring Santa Rosa's Council still works that way. Windsor is a council-manager town of 26,344 people, per the 2020 Census. It was incorporated in 1992. A professional town manager runs day-to-day operations. The elected Mayor and Council set the budget, ordinances, and land-use policy.

The seat is open because sitting Mayor Rosa Reynoza is not seeking reelection. The town's own Council directory says so. Potter is running for Mayor, not for another Council term. Potter's filed statement says they have just finished "the past four years as your District 4 Councilmember." That is why District 4 is a separate open-seat contest on this ballot. The county roster shows the nomination period extended to August 12. No eligible incumbent Mayor filed again by the regular August 7 deadline. Massell's ballot designation is "Retired Educator." Massell qualified on August 11, near the close of that extended window.

Tanya Potter

Potter is Windsor's Vice Mayor. Potter also holds the District 4 council seat. Potter works as a police sergeant. Potter runs on public safety, roads and water systems, and closing the town's budget deficit.

Rick Massell

Massell's ballot title is "Retired Educator." Massell got on the ballot on August 11, 2026. Massell filed no candidate statement. No news story, web site, or platform was found for them.
