What to do if you experience problems at the polls today

Steve Cohen just posted this to Facebook:

“There are reports that people are being told in error that they have already voted when they show up at the polling stations today. If this happens DO NOT LEAVE. Ask for a provisional ballot. You will be asked to fill out an affidavit that says you haven’t voted yet. The poll worker will check the voter rolls to make sure you are registered and have not yet voted, and you will be given a card to vote on the machine.”
