Presidential hopeful Elizabeth Warren will be coming to Denver next weekend as Democratic contenders turns their focus toward crucial “Super Tuesday” states, the campaign announced Saturday.

The Feb. 23 event, which is free and open to the public, will be at the Fillmore Auditorium. Doors open at 1:30 p.m. with the event starting at 3 p.m. The campaign encouraged people to RSVP, as admission will be first come, first served.

Warren’s visit to Colorado comes as her chief rivals for the nomination announced stops in the Centennial State in the coming days.

Bernie Sanders, the Vermont senator riding high after a victory in the New Hampshire primary last week, will rally Sunday night in Denver. The second-place finisher in New Hampshire, former South Bend, Ind., Mayor Pete Buttigieg, is set to host a town hall Feb. 22 in Aurora.

Meanwhile, former Vice President Joe Biden is scheduled to visit Denver on Monday for a private fundraiser hosted by former Interior Secretary Ken Salazar. And Mike Bloomberg, the billionaire who entered the race late last year but has set his sights on “Super Tuesday” states such as Colorado, opened another campaign office in Denver last weekend and has poured millions into advertising in the state.

Warren, the progressive senator once a front-runner in the presidential race, is looking for a shot in the arm after disappointing finishes in Iowa and New Hampshire.

Colorado, however, remains tough to read because of a lack of public polling. The last publicly released poll in the state came in August, showing a tight race between Sanders, Biden and Warren nearly all within the margin of error. The dynamics of the race have shifted considerably since then.
