From a Pew Research Center survey released two weeks ago (h/t John Aravosis):
These numbers show that it's Barack Obama, not Hillary Clinton, who would face a tougher challenge consolidating the Democratic base as nominee.
I suspect these numbers reflect the Clinton campaign's negative attacks on Obama. They don't seem to have moved that much if any of his support to her, but it has had an impact on how her own supporters view him.
From the perspective of the Democratic party, this is the worst of all worlds: one candidate is attacking the other in futile effort to win over new support -- and in the process, creating an ever growing challenge for .
Unfortunately, the Clinton campaign doesn't seem to care about the effects of their strategy on the Democratic party. Still, there's a lot of time between now and November, and Obama has a key asset that Clinton does not -- strong support amongst independents. Ironically (given the Republicans for Clinton trend), Obama has slightly more support than Clinton amongst Republicans who will actually vote for him this fall.
