You definitely must be noticing a trend that the polls are beginning to revert to likely outcomes - case in point the We Ask America polls (WI, OH, VA). But, more interestingly, Real Clear Politics has meted out its regression to the mean slowly. When Obama-favorable national polls emerge, they are slow to place them on there. When Romney-favorable polls emerge, they are on there quickly.
More telling, is RCP's failure to drop the Gallup number that is pretty stale by now. Ohh, and they have conveniently left out the recent Purple Strategies poll showing Obama +1 nationally. If they subtracted Gallup, and added Purple Strategies, Obama's number would likely scare the crap out of the right. So, slow doses. Purple Strategies will likely be added to RCP closer to the end of the news cycle, so repubs life in the bubble of Mittmentum can go on just a bit longer.
Expect to continue to see polls, nationally, either show a tie, or Obama to win. Ras was probably getting nervous about having an outlier in the national poll, so today it is a tie. I wouldn't be surprised if it remains a tie all the way through the 7th. It's easier to say it was a tossup and hard to predict, than to predict a Romney win they know isn't coming.
BTW, this is my first post. Hello all! My O vote is already in the bank here in WI, in an especially red county.
