I think pretty much that Obama is done for. On the other hand, many were writing off John Kerry before Iowa and New Hampshire too. A Hillary scream could be just the ticket for Obama. ;-)
Which teaches us there's a huge difference between the press-preferred candidate and the voter-preferred.
Dean was a media darling, and now Obama is, but behind that curtain, actual voters are usually sober.
They will not vote for Barack, Hussein or Obama. Not now and not in 4 or 8 years.
