Zogby: Clinton 'heading for the exit'
To all intents and purposes the race for the Democratic nomination is over.
Senator Obama needs slightly fewer than 200 delegates to pass the winning post and there are more than enough pledged delegates remaining to be elected, and super-delegates waiting to put him over the top.
....
Where do we go from here? My understanding is that probably today, but certainly within 48 hours, about 30 super-delegates will endorse Mr Obama. That should give him further momentum.
Mathematically, this will widen the gap between him and Mrs Clinton. He has a bigger share of the popular vote, more pledged delegates, and will now overtake her in terms of super-delegates too.
Here are the reasons:
There really is no mathematical chance for her to win
Her campaign is virtually out of money - and it will be difficult for her
to raise significant amounts of money after last night
Not enough happened last night to give her any hope, so continuing would
only give the appearance of wanting to damage Mr Obama
Another problem she faces is that she is not perceived as a strong general election contender, because of her high negative poll ratings.
I have no evidence that she will throw in the towel, or when she will. She is a Clinton and the Clintons do not have the word "lose" in their playbook - but these are the things I am hearing from supporters on both sides.
