D-Day's Must-Read Post on Obama's ground game and the polls

D-Day has a must read post.

Over the past few days, a fair number of high-profile progressive bloggers have been, to put it mildly, flipping out about Barack Obama's campaign style and his chances in November. ... I think they all make points which are valid to varying degrees. But they are failing to totally account for the X factor of the election, an X factor which is going virtually unmentioned throughout the blogosphere - the historic ground effort that the Obama campaign is banking on to win. It is not without peril, but it is a very new thing, and I think we have to understand it if we want to understand the twists and turns of this election.

I was attempting to excerpt it for a comment elsewhere and found that I'd highlighted at least 3/4 of it and it's long. So just go read it.
