Says an unnamed former Edwards operative about the possibility of an endorsement:
"My gut instinct, at this point: He’s probably going to remain neutral and sort of try to play on that Al Gore status as party elder."
The above-the-fray thing is a perfectly reasonable position for a party elder while the nomination is still in doubt. But very soon (perhaps now) it won't be. If one candidate's only plan for winning is to cause enough chaos to raise questions about the legitimacy of the nomination, it's proper for party elders to avert such a disastrous outcome. If you care about the party, that's the proper thing to do. And as many people have convincingly argued, that's what things look like for the Clinton campaign at this point.
