As far as election predictions are concerned, all I can say with any conviction is that the polls are probably correct and Democrats likely lose control of the House, if not the Senate as well.
Even in the best of times, the U.S. Congress is a three ring circus, and in case you hadn't noticed these aren't the best of times. Competent government has always taken a back seat to partisan politics, and who knows if this conundrum is going to play a historically greater role than it has in the past. The only thing we can say for sure is that America is in desperate need of competent government and we aren't going to get it.
Other than that, both sides will probably claim massive voter fraud in every close race. It's become de rigueur, and no election is really complete without it. Considering all the potential law-suits, it probably won't be until well into March before the next Congress is fully seated - which ought to add considerably to the mirth and merriment.
You are voting Democrat, aren't you?
