When do polls close in Colorado?

Colorado votes by mail: county clerks mail a ballot to every active voter, and 7:00 p.m. Mountain time on Election Day is the deadline to return a ballot to a drop box or voter service and polling center and to vote in person. A mailed ballot must be received by the county clerk by 7:00 p.m. on Election Day; postmarks do not count. Voters who are in line at a polling location by 7:00 p.m. are allowed to vote.
