"The amount of voter fraud is inconsequential. The effects of disenfranchisement? Admitted even by the proponents of these ID measures."
Voter fraud IS disenfranchisement. For every fraudulent vote, one legitimate voter who cast a ballot a different way has had his or her vote nullified - effectively disenfranchising them. So, no, voter fraud is NOT "inconsequential", it has the exact same consequences as disenfranchisement. It's just harder to pick a specific person who lost their vote.
