the question is not "why wouldn't you be required to identify yourself?", the question is "why is it that a concealed weapons permit is a more valid form of ID than a state issued school ID or passport?"

i don't know of any state where you are not required to prove you live in the precinct you're voting in, at least as far as registering to vote goes. once you are registered, it's incredibly difficult to impersonate someone else and vote as them. the vast majority of the ID laws that have been passed are designed by nature to suppress the votes of minorities and students for the sole purpose of preventing democratic-leaning voters from reaching the polls. from Pennsylvania, to North Carolina, to Georgia, to Texas and Wisconsin, a republican has made a statement to the effect that these laws are going to deliver votes to allow republican candidates to win, or that the law is going to keep "the wrong people" from voting (i.e. typically blacks and students). the idea that there is some sort of fraud to be prevented is a farce to give the law a neutral cover that allows republicans to conceal the true agenda of suppressing the democratic vote.
