The Maricopa County Elections Department in Arizona reported the issue as early voting for the state primaries continues.
Voters are directed to a web page to find unaffected polling places.
Early primary voting has been open since July 3, with the official primary election on July 30.
These primaries will significantly impact the balance of power in the U.S. Senate and House, with key races including Kari Lake vs. Mark Lamb for the Senate and 6 Republicans vying to replace Debbie Lesko in the 8th Congressional District.
This country may not survive another election season of voting machine irregularities.
