What’s your source for the statement that 1 in 5 registered Dem voters are intending to vote for Romney?
There have been more than 1 poll so far taken where the internals have shown this.. have to look at the details, not the conclusive numbers.
Also, polling JUST in the swing states (IE only polled voters in swing states) showed Romney up 10.
Don’t believe the nonsense you are being fed guys... Obama, and democrats in general are facing an electorial DISASTER. 2010 was the tip of the iceburg.
