I see no problem with this!
Fragment of a discussion from Comments:Pennsylvania courts to decide on controversial voter ID law
There's a difference between taking reasonable steps to tackle voter fraud, and disenfranchising people who may-well not vote as you would hope.
The timing of this move to require a very constrained set of ID for voting is, quite obviously, aimed at disenfranchising. Had it been introduced 18 months ago, thus allowing a reasonable time for people to obtain the required ID, it would be a legitimate move.
