With Democratic primary campaigns well under way for 2020, presidential candidate Sen. Bernie Sanders (D-VT) will make his first Colorado appearance Monday, September 9, for a rally in Denver.

The event begins at 6 p.m., with doors opening at 4:30 p.m. The rally will be held at Civic Center Park, 101 W. 14th Ave, in Denver.

The event is free and open to the public, although attendees are encouraged to RSVP ahead of time to ensure entrance.

Sen. Kamala Harris (D-CA) campaigned in early August in Denver, and Sen. Elizabeth Warren (D-MA) held a campaign event in April in Aurora.

Former Vice President Joe Biden plans to make a stop along his campaign trail in Denver in late September.

Sanders holds the lead in Colorado at the moment at 26 percent of support among Democratic primary voters, with Biden and Warren at 25 percent and 20 percent respectively, according to an August Emerson poll. The same poll shows Sanders leading significantly among voters ages 18-29 and 30-49 in Colorado.

This will be Colorado’s first year holding a primary rather than a caucus in a presidential election in almost twenty years. The Colorado primary will be held on so-called “Super Tuesday,” March 3, 2020.

Super Tuesday holds special significance due to the large number of primaries being held on that day, which is a game changer for candidates’ positions in the race. Colorado’s participation in Super Tuesday will likely create a positive impact in increased candidate outreach in the state.
