Lt. Gov. Donna Lynne on Monday became the third Democrat to deliver petitions to qualify for this summer’s primary ballot, turning in roughly 25,000 signatures to the Secretary of State’s Office.

Lynne’s campaign made the announcement on Monday in an email. Lynne, who is also Chief Operating Officer, joins fellow Democratic candidates Mike Johnston and U.S. Rep. Jared Polis as candidates who have submitted petitions. Johnston is the only gubernatorial candidate to have his signatures verified so far.

Candidates will have until 5 p.m. on Tuesday to turn in petitions  to the SOS office. Republicans Victor Mitchell, Walker Stapleton and Doug Robinson have also submitted signatures and are awaiting verification.

The release from Lynne’s campaign said she, “crisscrossed the state” to speak to voters across Colorado. She needed to collect 1,500 signatures from registered Democrats from each of the state’s seven districts in order to qualify for the party’t primary ballot. Candidates typically submit many more signatures than required to compensate for potential ineligible signatures. In Johnston’s case 12,698 of 22,585 submitted signatures were deemed valid.

“Moving forward, I will continue to reach out to all corners of the state to listen to voters and share my plans to improve health care access and affordability, ensure economic growth doesn’t leave middle-class Coloradans behind, extend educational opportunity and improve outcomes, invest in our infrastructure, and protect the state’s air and water,” Lynne said in the release.
