From First Read:

Just Asking: But when is Clinton going to talk an Obama superdelegate into switching? Do they have a few in their pocket for May 7 if they somehow sweep Tuesday’s contests? For now, it seems it’s Obama who continues to have more lure to superdelegates and continues to find the occasional Clinton switcher. The addition of Andrew to Obama’s fold is a big deal because of his title and because of the fact Bill Clinton appointed him to the job in the ’90s. But it’s what Andrew said that could have resonance: “I am convinced that the primary process has devolved to the point that it’s now bad for the Democratic Party.” Does Andrew become a Clinton superdelegate whip at this point?
