My wife is a poll worker today.
For her, election day really started last night when she and the other workers set up the polling place. Then she had to get up at 4:00 in order to be at the polls by 5:15 in order to open the polls by 6:00.
Tonight the polls close at 7:00, but anyone in line by then gets to vote. Closing the polls takes an hour or more because everyone is super tired by then. Then you have to drive the ballot box over to the registrar.
So an 18 hour day for my wife today.
