Another lawsuit has been filed over Colorado’s ban on ballot selfies.

This time, the plaintiffs are the Colorado Libertarian Party’s communications director and two Denver voters, who claim they already have shared their ballots on social media or with family members.

The lawsuit, filed Tuesday in U.S. District Court in Denver, asks a federal judge to declare the state law unconstitutional and to bar Colorado Attorney General Cynthia Coffman, Secretary of State Wayne Williams and Denver District Attorney Mitch Morrissey from prosecuting anyone who has shared their completed ballots with anyone else, including on social media.

All three are defendants in the lawsuit.

Caryn Ann Harlos, the Libertarian Party spokeswoman and a representative on the party’s national committee, said in the lawsuit that she had planned to record a video of herself filling out her ballot and explaining why she was voting for Libertarian candidates. However, she cannot do so because of the threat of prosecution.

Kiyomi Bolick, a Denver voter listed as a plaintiff, posted her completed ballot on Facebook but removed it after being contacted by an acquaintance in the attorney general’s office, the lawsuit said.

Andrew Madson, another Denver voter who is a plaintiff, sent ballot selfie pictures to family members but decided not to post the picture on social media to “avoid heightening his risk of prosecution,” the lawsuit said.

On Monday, Republican state Sen. Owen Hill joined an 18-year-old college student in a similar federal lawsuit.

The fracas over ballot selfies erupted last week when Morrissey’s office issued a news release under the heading “Reminder: Ballot selfies are illegal in Colorado.” The release cited the state statute that prohibits voters from showing a completed ballot to anyone.
