Primary Election Information

If you are a registered voter in Colorado, you should receive a mail-in ballot for the primary election in early/mid June.

The ballots are due on Tuesday, June 26 by 7 p.m.

If you are registered as unaffiliated (a.k.a. independent) you will receive 2 mail-in ballots, one from each major party. You can only return one ballot so will need to decide which one to discard.
