The rise in early voting has prompted Pima County to cut back on the number of polling places for the Aug. 28 primary election.
Pima County officials say it's the first time the county has cut back on polling places. More than 75 percent of votes are cast by early ballots in Pima County. Elections officials say with so many people voting by early ballots fewer polling places are needed.
In Maricopa County more than half of all registered voters are signed up to receive early ballots.
