Early voting continues to be popular in Pima County as the last week before primary Election Day nears.

The Pima County Recorder's office says it mailed a record number of early ballots to voters for this election, with more than 220,000 requested.

Voters registered as independent, which means they are not affiliated with a political party, are returning their ballots faster than those who are in a party. More than 40 percent of independents who received early ballots have already voted and sent them back, according to figures from County Recorder F. Ann Rodriguez.

Among Democrats, more than 31 percent of early ballots have been mailed back, and more than 26 percent of the Republicans who received an early ballot have already voted.

Early ballots must be returned to the recorder’s office by 7 p.m. on election day to be counted. Officials recommend mailing them no later than Friday.

It is too late to request an early ballot, but there are several places to cast a vote in person before Election Day.

These early voting sites are open weekdays from 9 a.m. to 5 p.m., through Aug. 24. Addresses are for Tucson locations, unless another city is noted:
