City of Mendota
Mendota City Council
This person would hold one of three City Council seats in Mendota. Council members vote on city ordinances, the budget, and land use. This dataset could not confirm the council's total size. It also could not confirm how Mendota picks its Mayor.
Four candidates are running for three Mendota City Council seats on November 3. The incumbents are Joseph Riofrio, Victor Martinez, and Libertad "Liberty" Lopez. All three seek another term. They face challenger Oscar Rosales.
This person would hold one of three at-large City Council seats up this cycle. Mendota is a Fresno County farming city of about 12,600 residents in the San Joaquin Valley. It calls itself "The Cantaloupe Center of the World." Two things are still unconfirmed. One is whether Mendota's Mayor is elected by voters or picked by the Council from its own members. The other is the total size of the Council. The city's own site, ci.mendota.ca.us, returned only a broken-setup error every time. Two look-alike sites turned out to be other cities. Both cityofmendota.org and a "City of Mendota" Facebook page belong to same-named cities in Minnesota and Illinois. Neither is California's Mendota. Wikipedia names Victor Martinez as the sitting Mayor. He is one of the three incumbents here. He is running for a council seat, not in a separate Mayor contest. That fits a Council-picked Mayor but does not prove one. Mendota has no elected City Clerk or City Treasurer in either Fresno County candidate document.
Four names are on the ballot for three seats. This is a plurality race decided in one round. The three highest vote-getters win outright. Two incumbents list their ballot label as simply "Incumbent," with no job named. The third incumbent, Libertad "Liberty" Lopez, filed as "Clinician and Mother" instead. Fresno County's own incumbent-of-record listing confirms Lopez holds their seat by election. Lopez just did not use the word "Incumbent" on the ballot. Rosales filed as "Maintenance Operations Director." None of the four filed a Candidate Statement. No independent reporting compares the four or covers the race.
