After another election as a poll worker 515AM to 815PM I like idea of maybe Saturday 8am to 6 pm and Sunday 10 AM to 6Pm ( adjusted for time zones for unified closing times) would seem better.
Another suggestion for what would help was that if it be only Pres/VP and any US Senators. That it was two large pages both sides in our ward made the scanning awkward. Then there were voters who ignored other races and referendum issues, some very important, because that isn't where their focus was. A few voters were a bit intimidated by the questions they hadn't focused on.
