Mrs. Sine_Nomine and I voted one hour after the polls opened. There was no line, but checking in was slow. My prediction is that turn-out will be light. The ballot had four sides (and was very long - Arizona). The props were so varied and confusing that my wife and I took prepared cheat sheets. Even then she muffed two votes. Since this was a complete the line ballot, she had them nullify those two votes.
I think interest is rather low, frustration with the voting process high, so I expect relatively few votes overall.
I am still expecting the GOP to hold the Senate and the House with losses in the margin in both places. If things go badly, I hope this will spur real conservatism in the GOP instead of RINO yakking about compassion.
Clayton, MO (St. Louis suburb) had about a 30-40 minute line for touch screen, 15 minute for optical scan. We had one "high maintenance" but he eventually got through the lines. No problems to report...
