Okay, I drive past three polling places on the way to work. I live in an extremely conservative area in Michigan and the closest polling place to me was packed. I'm talking a big church parking lot full plus cars parked up and down the road for a good 100 or 200 yards. The heaviest I've ever seen. The next place I drive past is still in a conservative area, but is on the edge of a college town. It was also very packed, the heaviest I've seen. The third place I drive past can probably be classified as somewhat urban. It wasn't packed at all. Maybe 5 cars in the parking lot.
I hope this means that conservatives are coming out in droves. The worst case is if it's a bunch of ignorant kids coming out in droves.
