We're now hearing around three dozen Hillary supporters a day make the case for her as Veep, but it's pretty seldom that you hear a prominent Obama supporter like the Reverend Jesse Jackson doing the same:

"While clearly the choice of a running mate is his and that right should be honored, I thought she made a powerful case for her eligibility," Jackson said in a phone interview with The Associated Press.

"As he surveys the field, it must be someone who is compatible with him philosophically, someone who is loyal to his agenda and someone who brings a constituency that matters and the capacity to become the next president, as the Constitution requires should disaster strike," Jackson said.

Clinton meets those requirements, Jackson said. "She may not be the only one who does, but she certainly does," he said.

This stops short of an outright call to make her Veep, so it isn't really that difficult or risky a thing for Jackson to say, but his effusiveness is noteworthy.

Indeed, as noted here before, the tell will be whether Obama supporters start making such a case in significant numbers. It seems unlikely, now that Obama and his advisers have clearly signaled that they don't want to be pushed in this -- or any -- direction as they try to decide who to pick.
