Marc Ambinder writes about an RNC memo "that portrays the Democratic Party in a state of disarray and claims that legions of Hillary Clinton voters are poised to jump to John McCain." As Marc says, "privately, many Democrats would agree that that 'united' is not the best adjective to describe the party right now." If anything, though, I think this ought to give McCain serious pause. How is it that he's in a dead heat with an opponent who's party is an a maximum state of disunity?

It's hard for me (or anyone) to know for sure to what extent currently disgruntled Clinton supporters will unite around Obama. But everyone knows that some of them will do so. Obviously events can occur that will change people's opinions of Obama and McCain, but one's generic assumption has to be that the Democratic Party will grow more united between now and November and given current polling that spells trouble for McCain.
