A record-breaking number of El Paso County residents cast their ballots in Tuesday’s primary election, according to county officials.

As of about 2 p.m. on Monday, the county Clerk and Recorder’s Office had received ballots from 100,459 of its roughly 390,000 active registered voters. Of the ballots returned, 24,502 were from Democrats, 52,673 were from Republicans and 23,279 were from unaffiliated voters.

Officials are attributing the “all-time high” number of county voters who have cast ballots in the primary to a new statewide policy that allows unaffiliated voters to participate in the primary election for the first time, said Kristi Alfonso, a spokeswoman for the Clerk and Recorder’s Office.

Unaffiliated voters were mailed ballots for both primaries but can only return one. By state law, if a voter returns both ballots, neither ballot counts.

About 86,000 county residents voted in the 2016 primary election, Alfonso said in an email.

As of about noon on Monday, ballots had been received from about 691,000 voters across Colorado. Of those ballots, 267,620 ballots were cast by Democrats, 261,686 by Republicans and 161,560 by unaffiliated voters, the Secretary of State’s Office said in a news release.

Ballots must be received by the county Clerk and Recorder’s Office by 7 p.m. on Tuesday.

Anyone who hasn’t cast their ballot should drop it off at one of 15, 24-hour drop-boxes across the county.

Ballot drop-off locations include the Colorado Springs City Administration Building at 30 S. Nevada Ave., Library 21c in northern Colorado Springs, the Fountain Police Department, the Falcon Fire Protection District, Manitou Springs City Hall and Monument Town Hall.

Anyone who did not receive a ballot, needs a replacement ballot, or would like to register to vote and vote in person should visit one of the county’s seven voter service and polling centers.

Centers are at Clerk and Recorder’s main office at the Citizens Service Center, 1675 W. Garden of the Gods Road; the North Branch at 8830 N. Union Blvd.; the Downtown Branch at 200 S. Cascade Ave., the Southeast Branch at 5650 Industrial Place; and the Fort Carson location at 6351 Wetzel Ave.; Monument Town Hall at 645 Beacon Lite Road and The Independence Center at 729 S. Tejon St.

All centers will be open Tuesday from 7 a.m. to 7 p.m.
