What kinds of voter fraud would photo ID stop? A) When someone claims to be a dead voter. This is fixed quite easily by another method - remove dead voters from the rolls. Fixing the problem that way prevents anyone from voting for that person even if they have a passable fake ID. B) Claiming to be someone who has moved This is fixed by cross coordination between voting districts - if when you register to vote elsewhere the voting authority in your new home informs the voting authority in your old home that you have registered with them, the voting authority at your old place can remove you from the rolls. C) Claiming to be someone who is alive and a resident in that precinct- How often does this happen? Its kinda a stupid thing to do entirely, because if the real voter shows up before you do - you're busted! Are there any cases of this happening? A & B can not only be prevented without asking for ID - they can more effectively be prevented. If you have an ID law - people can still vote for dead people if they have a good enough fake ID - if you remove the dead person from the rolls, then it doesn't matter how good their fake is! There are more effective ways to prevent most of the kinda of voter fraud that a photo ID law would prevent. Republicans aren't really interested in stopping fraud, though, they are interested in increasing the odds Romney and other righties will win, and that's it.
