You can register to vote all the way until Election Day in Colorado, but Monday is the last day to register and still get a ballot in the mail.
According to the Colorado Secretary of State, 866,668 Coloradans have already voted as of Monday morning, which is about 23 percent of all registered voters and also, by chance, a palindrome. Democrats continue to lead the early voting, accounting for 38 percent of returned ballots.
You can register to vote or check your voter registration here.
If you prefer to vote in person or if you register after today, you can vote at a service center. Denver's locations are listed here.
What happens to your ballot after you send it in? Andrew Kenney went behind the scenes at Denver Elections. Lasers are involved.
