Also, something I did not consider is that AFAIK Americans don't have a national ID card. Is there some other ID except a driver's license ? what if someone doesn't have a car ?
I wouldn't say the solution is to forgo the ID but it is a strange situation. Seems like a leftover from the old west when everyone knew everyone in the area by sight.
and you get an ID that doesn't allow you to drive instead of a Driver's license (commonly called a 'State ID'. In my opinion, this is pricier than it should be most places. costing about the same as a Driver's license without requiring the state to test you for anything. I think most people would be up for making this much easier for citizens to do, or for anyone to do, if the ID had a citizenship demarcation.
Of course, having an ID is useful for a lot of things besides voting (buying alcohol or cigarettes, travelling, picking up prescriptions or going to the doctor, etc.) It seems like it would be very difficult to exist without an ID in our society, which is why so few law-abiding citizens even attempt it.
