there are more recent ones... and im not even saying that i personally believe them. but the author states that this is not backed up by fact - and well there are several polls (including exit polls) that say otherwise.
I'm just saying that it's an arguable point... Even in the worst polls the vast majority of Clinton-supporting respondents said they would vote for Obama and vice-versa...
The head to head polls reflected disunity within the party but not really widespread defection, necessarily.
It was a real problem that warranted Obama reaching out to Clitnon supporters (as he has) and Clinton breaching the gap herself (as she has) but it's reasonable to say the media overplayed the topic, even with respect to the limited polling data available.
To me the PUMA folks are a fringe that just makes lots of noise and they do not represent any kind of coherent demographic.
