I sure hope you're right, but I don't think the ACORN and dead voters are out of bed yet... they have yet to get their busloads mobilized... ;-)
One tactic is to come up with a reason to demand that the polls stay open later ("irregularities," large, late crowds, etc). Then, based on internal polls, they determine how many "new" voters and "dead" voters they will need to ship in or make up.
