How do they know, from an on-line vote, whether you're a resident of Louisiana? All they ask for is your date of birth (I give a different one each time). I think they record the computer it's coming from (I figure that's how they must have known when I tried to vote more than once in the same day), but even if they could track down that this computer is in Michigan, how do they know I'm not just visiting or a student or a Louisian-ite(?) with some other valid reason to be here now?
