At my precinct, they must have been expecting lots of crossover voters. They had a different line for crossover voters, and they had special "stalls" set up for us. That board on the toilet rocked around a bit, but it was OK I guess. Turnout was high, and I know space was tight!
Also, when we finished voting, they even had a special ballot counter for the crossover ballots! It looked like this -- was it the same way at your precinct?
No, we had touchscreen. No paper, no muss, no fuss.
