Because everybody else does. I have to show my driver’s license every time I vote.
You shouldn't have to, that's the point. I mean, it's nice that you are white and you can afford to get one with your current address and stuff, but some people can't.
Why would a poor person change addresses any more than anyone else?
I'd ask if you were kidding, but I keep forgetting you live in some lilywhite world where if you encounter a minority at all, you quickly rush to the other side of the street.
