Yuma County marks 90-day primary deadline, sets 2026 election schedule

Miss June 22 at 11:59 p.m., and you will miss the window to vote in Yuma County’s July 21 primary. Arizona Secretary of State guidance says that is the last day to register for the election, and anyone who waits past that deadline will have to sit out the primary and look to November instead.

Yuma County has already laid out the rest of the calendar around that deadline. The candidate filing period for the primary ran from February 21 through March 23, the 10-day challenge period ran from March 24 through April 6, and write-in candidates still have until May 22 to file. Public logic-and-accuracy testing is scheduled for June 17 at 10 a.m. and June 18 at 2:35 p.m. at the Yuma County Administration Building, 197 S. Main St. in Yuma, a step county officials use to verify that voting equipment is working before ballots are cast.

The biggest practical change for everyday voters is where to go and what ballot to ask for. Yuma County says it uses vote centers, which means any registered county voter can cast a ballot at any vote center, regardless of precinct. The county’s two mega-centers are the Yuma Civic Center and St. John E. Neumann Catholic Church in the Foothills area, and officials say those sites are designed with twice as many voting machines to help with long lines. County election materials say the system is meant to make it easier for voters spread across Yuma, San Luis, Somerton, the Foothills and other communities to vote without being tied to a traditional neighborhood polling place.

County voter FAQ materials say letters will go to all registered voters 90 days before the primary with information about both the primary and general elections. Voters on the Active Early Voter List who are not registered with a recognized party will receive a form to choose a preferred party ballot. That detail matters for independents and voters with no party preference, because Arizona law requires them to pick one qualified party ballot in a partisan primary. Guidance from Secretary of State Adrian Fontes’ office says no-party voters may choose among the recognized primary ballots, and Recorder David Lara has reminded residents that independents must choose Democrat, Republican or No Labels if they want a primary ballot.

The July 21 primary will also decide local offices that shape daily government in Yuma County, including Clerk of Superior Court, constables, justices of the peace and several Superior Court judge divisions. For voters trying to avoid last-minute confusion, the message is simple: check registration now, choose a ballot if party rules apply to you, and do not wait for the June 22 cutoff.
