Good. High turnout is something that benefits the society, because it gives more people a vested interest in the results, and hence a reason to be informed.
Not surprisingly, the turnout has increased the most on the Democratic side of the primary, undeclared voter can declare when they go into vote, and it looks like there may be shortages of ballots.
I think that this means a long night before all returns are in, but they will probably have a winner declared by 9:00pm on both sides.
