Hillary Clinton’s campaign announced the Democratic candidate for president will hold a public event Tuesday at the Boulder Theater.

According to an invitation sent to supporters, doors are set to open at 10 a.m. Tuesday for a meeting to discuss ” the issues that keep Coloradans up at night and how she’ll address them as president.” Clinton is slated to take the stage at 11:30 a.m.

The event is free but people wanting to attend are asked to RSVP at hillaryclinton.com/events/view/?id=898481. The Boulder Theater, 2032 14th St., can accommodate between 850 and 1,000 for public events, according to its online rental guidelines.

Boulder police spokeswoman Shannon Cordingly said Thursday the department was working in concert with the U.S. Secret Service in coordinating security efforts for the visit.

Clinton also is set to appear at a previously announced private fundraiser on Tuesday at the Boulder home of Jennifer and Mo Siegel, founder of Celestial Seasonings.

That event is scheduled for 12:30 to 2:30 p.m. and her campaign is asking for a $2,700 donation from those who attend.

The former U.S. senator and secretary of state is running for the Democratic nomination for president. Colorado’s Democratic caucuses are March 1.

Clinton will be the third Democratic presidential candidate to visit Boulder this fall. Vermont Sen. Bernie Sanders spoke to some 9,000 people on the CU campus Oct. 10. Former Maryland Gov. Martin O’Malley visited the campus Oct. 28, the same day that CU hosted 14 GOP presidential candidates in a debate presented by CNBC at the Coors Events Center.

The former first lady’s visit will come fresh on the heels of a sobering report on her prospects in Colorado.

A new Quinnipiac University poll released Wednesday showed the Democratic front-runner for the 2016 presidential race trailing the top three leading Republican contenders by 11 percentage points or more in Colorado, which is again expected to be a pivotal swing state.

In that poll, Florida Sen. Marco Rubio led Clinton 52 percent to 36 percent, which was the biggest gap. Retired neurosurgeon Ben Carson would also win a head-to-head matchup, the poll indicated, boasting a 52 percent to 38 percent advantage over Clinton. Donald Trump had a 48 percent to 37 percent edge over Clinton in that same poll.

Tim Malloy, the assistant director of the Quinnipiac University Poll, termed the results a “chilly if not frigid reception” in Colorado for Clinton.

Within the Democratic field, however, Clinton’s picture is far more rosy in the Quinnipiac poll. Clinton leads the pack in Colorado with 55 percent, followed by Sanders with 27 percent, O’Malley at 2 percent, with 15 percent undecided.
