June 2020 State Primary Election


Translate This Page


Colorado’s June 30 State Primary includes party primary races for U.S. Senate, House of Representatives and state legislative seats. Denver voters have the opportunity to nominate candidates to compete in the November General Election for those seats. Some important things to know:

Voters registered as Democrats, Republicans, Libertarians or Unaffiliated can participate. There are currently no other minor party contests for the state primary.

Unaffiliated voters without a preference will receive both major party ballots but may only return one. If both ballots are cast, neither will count.

17 year-olds may be eligible to participate. Voters who are 18 years of age by the November 3, 2020 General Election can vote in the state primary.
