Presidential candidate Bernie Sanders will speak at Denver’s Civic Center Park on Monday evening — his first campaign stop of the year in a state that backed him in the 2016 Democratic primary.

Doors open at 4:30 p.m., and the event starts at 6 p.m. It’s open to the public and doesn’t require tickets, but attendees can RSVP on the Sanders campaign site.

The first Colorado poll of the 2020 presidential primary season suggests Sanders remains popular here, in a statistical tie at the top with former Vice President Joe Biden, who has been leading most national polls. Elizabeth Warren, who came in third, has visited the Denver metro area, as has Kamala Harris.

In an interview with The Denver Post on Friday, Sanders said he won’t be endorsing in the Democratic primary for Colorado’s 2020 U.S. Senate race. Former Gov. John Hickenlooper, who recently switched from the presidential to the Senate race, jabbed Sanders during his run, including in a speech denouncing socialism.
