Possibly North Carolina, Florida, and Ohio. Those states always seem to poll more Democratic than they vote in Presidential elections.
Strange, I always thought Ohio and PA polled pretty normally (with normal referring to 2000/2004 - yes I know Gore underpolled in 2000, but part of that was due to the last minute shift and him publicly withdrawing everyone).
Florida is always going to poll weird and usually too Democratic.
You missed Virginia.
Actually, this election is quite confusing in many ways. Somehow I suspect a lot of polls may be off. I think that's the answer Al wanted, right?
