Walk in voter fraud is incredibly rare. Much much less than mail-in absentee voter fraud. There are places where a person has to go over 100 miles to get a state id. They aren't lazy, they have jobs they can't get time off from to make a day trip. And no car in which to do it. Anyone who tries to disguise voter suppression as "preventing voter fraud" is probably part of a party that needs to suppress votes in order to win elections, and incidentally benefits from mail-in voter fraud the most. You know which political party that is.
