If you’re one of the millions of Colorado voters who haven’t yet cast their ballots in this year’s primary election, then you’ve come to the right place. 

You have until 7 p.m. on June 28 to vote, whether that’s by turning in the ballot that was mailed to you or voting in person. (It’s too late to mail back your ballot. You should use a drop box to ensure your ballot is counted.)

We’ve put together this guide for the procrastinators voters who are waiting until the last minute to weigh in on the important local, state and federal primary races being decided this month. Most of the action is in Republican primaries. 

We’re also sharing some stories that ran in our Unaffiliated newsletter, which is normally reserved for premium Colorado Sun members. (Sign up here to get The Unaffiliated.)

(The Colorado Sun hasn’t written about all of the races being decided on June 28, but you will find plenty of information to help you fill out your ballot below.)

8th Congressional District

There is no Democratic primary. Rhonda Solis is already on the ballot for November.
