No good reason to run out of paper. To run out in the first half of the day is pathetic. Also no reason you couldn't have those people fill out a provisional ballet and then cure it. And lets not forget the ability to write down anyone's name who was denied a vote. They don't know how many because no one tried to keep a count.

1 guy with a tally board could keep track of people who came after they ran out with no names at all.

No one tried to get accurate facts, because "uncountable voters turned away" is a better narrative.
