For the first time ever, unaffiliated voters in Colorado will get to cast a ballot in a partisan primary, ahead of the June primary. Unaffiliated voters will be sent two ballots and must choose to vote in either the Republican or Democratic primary. Secretary of state Wayne Williams says, "if you're unaffiliated, you can designate which ballot you want ahead of time, so you don't get two ballots in the mail" And if you cast both ballots, neither one will be valid.
