If, however, Republican voters are generally unaware of the high frequency of minorities, the poor, and the elderly lacking IDs, they are blissfully ignorant of the real costs of getting an ID. Yes, the ID itself is free for the indigent (to comport with the 24th Amendment’s ban on poll taxes), but the documents one needs to get a photo ID aren’t, and the prices haven’t been reduced. Lost your naturalization certificate? That’ll be $345. Don’t have a birth certificate because you’re black and were born in the segregated south? You have to go to court.

Similarly, Republican voters — and perhaps most others — tend not to be aware of how hard it can be to get an ID if you live in a state where DMV offices are far away or where they simply aren’t open very often. One can only hope that would-be voters have access to a car or adequate public transportation, and a boss who won’t mind if they take several hours off work to go get their ID, particularly if they live in, say, the third of Texas counties that have no ID-issuing offices at all.
