Colorado passed the Voter Access and Modernized Elections Act in 2013, which required ballots to be mailed to every registered voter for all elections.
The law also continued to require counties to accommodate early in-person voting and on election day, shortened state residency requirements for voter registration to 22 days from 30 days, allowed for same-day registration and voting on election days and eliminated assigned polling places, replacing them with more accessible county voter service and polling centers.
The act was signed into law May 10, 2013, by then-Gov. John Hickenlooper.
Seven other states and the District of Columbia allow all elections to be conducted by mail including California, Hawaii, Nevada, Oregon, Utah, Vermont and Washington. Nebraska and North Dakota, meanwhile, allow counties to opt into conducting elections by mail. Thirteen other states allow mail elections in more limited forms.
