Colorado Amendment C (also known as the Charitable Bingo and Raffles Amendment) was a 2020 referendum to amend Section 2 of Article XVIII of the Colorado Constitution. The amendment would have changed the rules governing the conduct of charitable gaming activities (bingo, pull-tab games, and raffles). The amendment failed because it did not receive the 55% of the valid vote required to add to the Constitution.
The amendment appeared on the ballot as follows:
The amendment was supported by the Colorado Charitable Gaming Association. Boulder Weekly, The Vail Daily, The Durango Herald, The Steamboat Pilot & Today, and The Journal-Advocate and The Fort Morgan Times ran editorials in support of the amendment.
The Colorado Springs Indy ran an editorial in opposition of the amendment.
