Didn't create any problems at our precinct........I think this only would effect someone that shows up at the incorrect precinct (their name is not in the registration log for that polling place), and the poll workers have to look up their correct polling place.
In a way, it might work in our favor........someone too stupid to check the location of their assigned polling place is obviously too stupid to cast a ballot.
I don't know if this is state-wide, but our polling location is printed on our voter registration card, and we are mailed a new one if it changes........you have to present the card to get a ballot.
