Colorado trans athlete ban measure too close to call
The gist
Colorado's Proposition 134, barring transgender girls from girls' school sports, led 52.2% to 47.8% with 73% counted.
The measure changes state law, not the constitution, so lawmakers could rewrite it.
How it unfolded
- Mar 17, 2026A trans athlete ban was set to appear on the Colorado ballot in November, focused on school sports.
- Oct 16, 2026Axios' voter guide described Proposition 134 as asking whether biological sex should determine who can play on girls' and women's school sports teams, from elementary through college.
- Oct 24, 2026AP reported Colorado and Washington voters could ban transgender girls from girls' school sports, the first time the issue goes to voters; a June Quinnipiac poll found about 7 in 10 registered voters think transgender women and girls should not be allowed on female sports teams.
