AURORA | The June 30 Primary Election in Colorado will be like none other in the wake of the coronavirus pandemic.

The main event: The Democratic primary race between former Gov. John Hickenlooper and former state House Speaker Andrew Romanoff. The winner takes on first-term GOP Sen. Cory Gardner. Gardner, who has lagged in polls for months, is frequently tabbed by pundits as the most vulnerable GOP senator in the 2020 Election cycle.

But it isn’t just the race that makes this primary election different than any others, it’s a bevy of factors.

Mail-in ballots have been a reality in Colorado since 2014. Voters began receiving their ballots for the June primary  weeks ago and decide who will represent their political parties in the November General Election. Most races are unopposed.

What’s new is that this is the first statewide general election implementing a new state law allowing unaffiliated voters to choose candidates in party primaries. 

The three counties that have Aurora residents — Arapahoe, Adams and Douglas — all were mailed ballots the week of June 8.

Voters who have not returned their ballots by Tuesday must now do so in person at any of several drop-off sites to ensure they’re counted.

In-person voting is still an option in each county, however, even for voters who aren’t registered.

In the primary format, each registered Democrat, Republican and Libertarian receive one ballot, while unaffiliated voters get two and return one. Candidates for state senators, representatives, county commissioners, district attorneys and University of Colorado Regents dot this ballot, as voters will decide who will advance to the November General Election.

Ballots must be received by 7 p.m. on Election Day on June 30 to be counted, or in-person voting must be underway.
