It’s clear to Edwards, or at least it must be, that he isn’t pulling in above 20% frequently enough to make a good campaign stick. The emphasis is now completely on the other two and it is unlikely that when pressed super delegates are going to risk their vote by splitting it between three when it could mean their second choice is beaten by their third. With so many super-delegates Edwards must know that a) he doesn’t have a chance at conference and b) that he now holds a good sway of power.

If he endorses Obama then that will really push things his way I’d say, as his list of supporters is impressive and growing. Anything less than this for Obama, however, demographically and politically will mean Clinton is almost certain to have much more breathing room.

I don’t see how much influence he has left after a pretty poor showing so far. He has some capacity to push some campaign money one way or another – but from what I can see thats about it.

The debate between clinton and obama doesn’t reflect a left/centrist split well enough for him to deliver his vote to one or other of them.
