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.
