March Presidential Primary Election in Colorado

March Presidential Primary Election in Colorado

New rules for Unaffiliated voters and 17-year-olds

Colorado will hold its first Presidential Primary Election in two decades on March 3, 2020. The State will still conduct a primary election for state-wide and local candidates in June, but a Presidential Primary will take place as a stand-alone mail-ballot election in March. Ballots will be sent to voters beginning February 10.

You must be registered as a Democrat, Republican, or Unaffiliated voter in order to participate. Democrats will receive only the Democratic Party ballot. Republicans will receive only the Republican Party Ballot. 

Unaffiliated voters will receive BOTH party ballots but may only vote and return one. If you return both ballots, both will be disqualified.

17-year-old voters who will turn 18 by the date of the General Election, Tuesday, November 3, 2020, may now register and vote in the primaries!

Register to vote online at, by mail, or in person at any Boulder County Clerk & Recorder’s Office. There’s one in Lafayette at 1376 Miners Drive.
