The testimony in PA against the voter ID law was very moving - people who were married recently (name changed on the license, but not on the voter registration? Sorry, you can't vote!) or people who can't get to one of the statewide DMV's to get a free ID (there are 67 counties - some don't even have a branch of the DMV, and there are only 5 in Philadelphia, and only one (!!) in Pittsburgh). After all, if they don't have a license, how can they get to another county to gete an ID?
It was a stupid law, enacted without enough time to put it into effect in a reasonable way. Initially, the free ID at the DMV wasn't even in the statute, it was added as an amendment. It had one and only one purpose - to stop poor, minority and young voters from being able to. I think there was some shmoe in the state house who actually said that it "cinched the election for Romney" when it passed.
And it wasn't revoked just delayed. You were still asked for an ID at the poll (I was, even though all the pollworkers know me), but if you didn't have one, you could still vote and it still counted. I think that counted as intimidation, myself. Bear in mind that you need to sign a registration form before you can vote anyway, and it has the signature you registered with for comparison, so you've already been ID'd that way!
Most of it was a poorly planned ploy, plotted by pernicious pricks.
