State Rep. Polly Lawrence, a Douglas County Republican running for Colorado state treasurer, turned in nearly 20,000 petition signatures Monday to secure a spot on the June primary ballot, her campaign said.

“Each of the signatures and the people behind them, willing to put their name literally on the line, means so much to me,” Lawrence told Colorado Politics. “Gathering signatures statewide is no small feat, and I’m looking forward to earning the vote of our Republican party in June.”

She’s one of six Republicans running for the office held by term-limited Walker Stapleton, a GOP candidate for governor and the second petitioning candidate to deliver signatures to the secretary of state’s office.

Real estate CEO Brian Watson submitted roughly 17,000 signatures at the end of last week. For statewide candidates, it takes 10,500 valid signatures from fellow party members to qualify for the June 26 ballot.

Alternatively, candidates can go through the assembly process, which kicked off Tuesday night at more than 3,000 precinct caucuses around the state. Candidates who go that route have to win the votes of at least 30 percent of delegates to the state assembly. The GOP’s meeting this year is set for April 14 in Boulder.

That’s how the other Republicans in the race are planning to get in front of primary voters. They are state Sen. Kevin Lundberg, R-Berthoud; state Rep. Justin Everett, R-Littleton; Routt County Treasurer Brita Horn; and Brett Barkey, the district attorney of Grand, Moffat and Routt counties.

Three Democrats are running for the office, which handles the state’s finances, takes care of returning unclaimed cash and property to residents and has a seat on the state pension system’s board.
