City of Commerce
Commerce City Council
This person would hold one of three at-large seats up this cycle. It is on Commerce's five-member City Council. Terms are staggered and last four years. They vote on city laws, the budget, and land use. The council picks one of its own members to serve as Mayor. It picks another as Mayor Pro Tem. These titles rotate rather than being separately elected. An appointed city manager runs daily operations. Councilmembers are capped at three full terms. Commerce voters adopted that limit in 2011.
Six candidates are running for three at-large seats on Commerce's City Council. They are incumbents Kevin Lainez and Mireya Garcia, and former Councilmember and Mayor Leonard Mendoza. The other challengers are Vanessa Haro, Nick Padilla, and Jaime Valencia. A third incumbent, Ivan Altamirano, was barred from the Nov. 3 ballot by a court ruling on Aug. 27, 2026. Voters may pick up to three, with no primary.
Council seats carry 4-year terms, staggered so three or two of the five seats are up each cycle -- this year it's three. Winners join two sitting councilmembers not up this cycle, Hugo Argumedo and Oralia Rebollo, to make five votes on city ordinances, the budget, and land use. The council then selects one of its own to serve as Mayor and another as Mayor Pro Tem -- titles that rotate rather than being separately elected -- and day-to-day operations run through an appointed city manager. Members are capped at three full terms under a limit Commerce voters adopted in 2011 by more than 72%.
That cap is why this race has six names instead of seven. Councilmember Ivan Altamirano -- appointed in 2012 and elected in 2013, 2017 and 2022 -- filed to run again, and the city clerk initially listed him as qualified. Former Mayor Lilia Leon sued, arguing a 2022 measure that extended council terms to match the state's consolidated election calendar didn't reset the three-term limit. On Aug. 27, 2026, LA County Superior Court Judge Joseph Lipner agreed, calling Altamirano's contrary reading "unpersuasive," and ordered the city clerk and county registrar not to place him on the ballot. Argumedo and Rebollo aren't up for re-election until 2028, when the same limit will eventually reach them too.
