We did not ask that specific question, because we were concerned with the people who needed the extraordinary measure of either using the vouching.... And frankly, they don't look at the voter identification card as extraordinary. They just thought, “The government sent this to me, and they have my name and address correct, so I'm going to bring it to the polling office.” I'm sure they didn't have any greater concern about it, other than that it was convenient and was enough to prove their right to vote.
