Much like Texas, today is the last day to register to vote in the state of Colorado.
You can verify if you are already registered here.
To register, access the registration form here — you’ll need to get it to your County Clerk by end of business today.
Because of the length of this year’s ballot (18 ballot measures in addition to the various candidates running for office), folks are being strongly encouraged to vote by mail-in ballot (link goes to PDF of form) or to vote early to avoid long lines on election day. Requests for mail-in ballots can be made up until October 28th.
