1) There is a way for all Americans (including the poor, minorities, indigenous tribes, the homeless, and people without a physical address) to obtain this ID without any prejudice, opportunity cost, or privacy implications 2) There is significant political will to rolling out 1)
Then I'm with you. If not as it currently is the case, then voter ID is a means of disenfranchising the vulnerable groups I mentioned in 1) and I'm opposed.
Update: You might argue that I'm contradicting myself in that voter ID law would be good and ensuring that the groups I mentioned were protected in 1) would be asking for perfection. My rebuttal would be that any scheme that allows for legal disenfranchisement of otherwise legal voters is not good at all.
No one, including partisan commissions established for no other purpose than validating this claim, has been able to provide evidence supporting this.
The documents you present for ID shouldn't be any more than you should present to vote... it's just a shortcut. Voter fraud is a significant issue... in many districts significantly more than the number of people who would be unable to vote because of complications.
