Colorado's flexibility in conducting elections is thought to be unique in the nation. The new election model allowed for all active voters to receive a ballot by mail, in person voting option for two weeks prior to and on Election Day, with an opportunity to register to vote or make an address change up to and on Election Day. In previous partisan elections, those who missed the registration cut-off or did not correct their address prior to going to the polling place were required to vote a provisional ballot. As a result of the change in model, there was an improvement in voter turnout and a substantial reduction in provisional ballots issued from previous general elections. While many states' turnout number declined, Colorado's improved and was the fourth highest in the nation.
