Here, when you register to vote they put you on a giant list. Then when you show up, you tell them your name and address, and sign next to your name on the list, then they issue you the ballot. No voter registration cards are given out. They are pretty good about keeping the lists in order, only once did a district bugger up my registration when I moved.
In Ohio, argh. Don't talk to me about Ohio's voting inconsistencies. I think the Ohio elections board just makes it up as they go along. Never had so many problems trying to vote. But it was in such a way that it could have merely been gross incompetence.
Where I went to college in PA, all the elections were completely controlled by the local...um, dunno what to call it. It wasn't exactly organized crime, because they didn't do a whole lot of that, but a handful of large extended families control everything, including elections. Temple U's law school used to use that particular county as a textbook example of political corruption, and they've had various functions taken over by the state a couple of times for corruption and gross incompetence. I remember showing up at the polls in my neighborhood, and because I wasn't from the local Italian/Polish/Irish syndicate, I was told that I couldn't vote because I "didn't really live here, so you're not registered." I could see my name on the list from the state right on his desk, I knew I had registered when I did my driver's license, I had a voter registration card, but the guy yelled at me to get out of his voting office, I wasn't registered. People tell me that Boston is corrupt, but they got nothin' on northeast PA.
