You recall correctly. All one needs is a cable bill, or failing even that, someone to "vouch" that he or she is eligible to vote. If one is in Racine (where 30 vanloads were schlepped into one polling place and another had a table run by DemonRATs who matched up ID-less people with people willing to swear to the lie), they're there forever because Racine refuses to even attempt to verify the information (a violation of state law).
One of the problems is that you don't need a photo ID to register, if you don't have one, an utility bill, or even a witness (someone who "vouches" for who you are) is acceptable. And if you are already registered, you don't have to do anything but state your name. No signature, no ID, no anything. So if I know for sure that my neighbor will not be voting, all I would have to do is show up at the polls and vote in his name.
Thankfully, at my precinct, we all know each other, but on election day, there was actually a line of people registering to vote. We also, for the first time in my life, had people outside the polling station with Kerry/Edwards signs standing on the side of the road. I live in a very small township (about a 1,000 voters), and I know just about everybody in town, I did not recognize ANY of them. They were from a union that doesn't even function in our area. There was "tons" of fraud in Wisconsin on election day, yet our wonderful Governor refuses to acknowledge it.
