DENVER, Colorado: A proposal has been introduced in the Colorado Legislature that would require residents to provide some sort of identification to prove citizenship when registering to vote. The measure is being proposed in order to prevent voter fraud, according to supporters of the measure. The measure has been assigned to the State, Veterans & Military Affairs Committee for consideration. The measure must then pass both chambers of the Colorado Legislature in order to be enacted. The measure would then take effect on the 90th day after the final adjournment of legislative session. 
However, according to the last section of the proposal, if a referendum is proposed against the measure and certified, it would not take effect if voters reject it during the 2012 general election.
