For the first time in Colorado, Unaffiliated voters will be eligible to vote in the Primary Election.  This is because Colorado voters approved Proposition 108 in 2016. 
  • Unaffiliated voters will receive two ballots in your packet, one Democratic and one Republican.
  • Choose only one ballot to fill out and discard the ballot you won't use.
  • Return your one voted ballot in the return envelope.  (Sending in two voted ballots will disqualify all of your votes.) Visit www.UChoose.co.gov for more information.
