Just kidding, of course, though Edwards moves from 17 to 19 and Obama moves from 19 to 17 in the latest Cook poll. As impressive as Obama's polling and fundraising has been, the dominant narrative of this as a battle between Clinton and Obama has been a bit silly.
More interesting in the poll results is the fact that Obama/Edwards supporters don't seem inclined to support the other one. Clinton is a popular 2nd choice as well as 1st one, and when Obama or Edwards are excluded from the poll their support largely shifts to Clinton.
And, yes, it's early and national polls are silly and when I find myself talking about this stuff too much I want to shoot myself in the face.
