Digby makes an excellent point about the Democratic primary fracas:
Personally, I don't think we'll have a tie much longer. It's hard to see how either candidate can unify the country if they can't demonstrate that they can unify the Democratic Party. Something has to break and I suspect voters will be the ones to do it.
The task of unifying the party is a real opportunity for Senator Obama to prove his quality, and if this weekend was any indication, he's on his way.
