Assume we stop 1000 people at random and see if they have a photo ID on them. How many of those 1000 people do you think would not have one?
Five, eight, ten at the most. Perhaps it would be difficult to find one or two out of the 1000.
Now assume that we find five or six out of the 1000. Now who do you think they would turn out to be?
Felons on the run who don't want to carry an ID? Homeless who have no address or ID or anthing else? Or, perhaps illegals who would have no right to vote in the first place?
Even the poor on food stamps most likely have some photo ID or how did they apply for the food stamps in the first place?
