Election Day is Tuesday, Nov. 3, but registered voters in Colorado will receive mail-in ballots after Oct. 9. With national concern about the veracity of mail-in ballots, Colorado has become a focal point. Colorado began statewide vote by mail in 2013, although some counties used it before that.

Voters and potential voters will have questions about how voter registration works, how mail-in ballots work, how ballots are counted and more. The Colorado News Collaborative and its members, including The Denver Post, want to answer those questions.

Here’s this week’s big question:

Do I have to request a ballot from my county clerk or the Secretary of State?

Not if you’re an active registered voter. County clerks automatically will begin mailing ballots to active registered voters on Oct. 9. A voter is considered active if they’ve voted in the most recent general elections or updated their address or other registration information

A recent nationwide mailer from the U.S. Postal Service insinuates that voters must request mail-in or absentee ballots. Colorado Secretary of State Jena Griswold is suing the Postal Service, saying the mailer is misleading and could disenfranchise voters.

A federal judge issued an order late Saturday to halt the mailings, and the Postal Service asked that he reconsider the order on Sunday. On Monday, the Postal Service said it already delivered 75% of the mailers.

You’ll need to fill out this form and take it to your county clerk or mail it to the Colorado Secretary of State.

What’s the difference between an “active” voter and an “inactive” voter?

As mentioned above, a voter is considered active if they’ve voted in the most recent elections or updated their address or other registration information. A voter is considered inactive if their county clerk receives returned mail to them marked “undeliverable.”
