Long lines are a pretty good way of making it impossible for some people to vote.
Imagine a person who has a long commute by bus to a kid's childcare and then another bus to work and then back to the kid, and then back to home; this person isn't likely to be able to spend 1,2,4, or 6 hours in line to cast a ballot.
So no, nobody at the poll said "Go away. You can't vote." But the system accomplished it pretty handily.
