Arizona GOP sues to force a new vote audit; attorney general rips the party's legal claims
The Arizona Republican Party is suing Maricopa County election officials to try to force an additional hand count of ballots in a way the party argues would "potentially result in a more precise sampling of votes."
But the Attorney General's Office, led by Republican Mark Brnovich, says the party has no legal basis for its claim.
County election officials must perform hand count audits using a random sampling of ballots to ensure the accuracy of electronic counts. The Maricopa County Elections Department already has completed one for the general election, officials said Monday, and it matched electronic counts exactly.
State law indicates officials should audit ballots from two county precincts or 2% of county precincts, whichever is greater, but that assumes a precinct-based model, where voters are assigned specific polling places they must use to cast their votes. For the 2020 general election, Maricopa County instead used vote centers, which were open to any voter throughout the county.
For vote center audits, the secretary of state's election manual indicates officials should consider each center to be a precinct for hand count purposes. "The officer in charge of elections must conduct a hand count of regular ballots from at least 2% of the vote centers, or 2 vote centers, whichever is greater," the manual states.
The Republican Party argues state law explicitly referred to "precincts" for a reason, and contends there is a "fundamental difference" between sampling 175 vote centers and 748 precincts.
