Erick Erickson, writing on *Red State*:
> Here’s a simple truth: the polls and polling trends are by and large accurate, but — and pay attention to the but — the polls are overestimating Democratic turnout. Those polls that presume less than a 2008 Democratic wave, which I think is most reasonable, have the race very close, though pretty much all of them have Romney still behind. The reality is that Mitt Romney is behind, but that does not mean this thing is over. It is close and Romney can very much still win this election. Finally, at long last, it also seems Romney has a message that can resonate.
That seems to be the most straightforward, and honest, explanation of what is currently happening with the presidential polling.
