Even after Hillary went out and campaigned with Obama:

A growing number of Clinton supporters polled say they may stay home in November instead of casting their ballot for Obama, an indication the party has yet to coalesce around the Illinois senator four weeks after the most prolonged and at times divisive primary race in modern American history came to a close.

According to a CNN/Opinion Research Corp. poll released Friday, the number of Clinton supporters who plan to defect to Republican Sen. John McCain’s camp is down from one month ago, but—in what could be an ominous sign for Obama as he seeks to unify the party—the number of them who say they plan to vote for Obama is also down, and a growing number say they may not vote at all.

We’ve heard a lot about the lackluster support McCain has gotten from conservatives in the GOP, and while those reports are absolutely true it seems as though Obama has no real enthusiasm advantage when it comes to his own party.
