"Can't be too careful"
Oh good, then I hope you support voter ID and no mass-mail-in ballots, since "we can't be too careful." >:)
Yeah, I don't know of any spy cameras that can zoom in that far and still be able to read. They'd also have to set it up exactly at the voting center, and given that 99% of voting centers aren't government buildings (school gyms, daycare centers [yes I've seen it before])it would be pretty hard to know in advance exactly where to set up the camera. Besides, if he wasn't AT the voting center then whoever was watching couldn't actually do anything to stop that guy, and if he did, guess what- that's voter fraud!
Oh, good! Somebody else who realizes how poorly most modern elections are run! Then hopefully we can coordinate our efforts to pass voter ID laws and other election integrity measures! Oh, wait... you're a leftie. You want to REMOVE election integrity safeguards to make it easier for you to... you know, the thing. ;)
