It's a veiled criticism of Obama:
"He serves as chair of the most important committee in the United States Congress," Clinton said of [Charlie] Rangel. "He didn't get there by leapfrogging. He got there by lots of hard work."
He can't help himself, can he?
(Correction: I misread the piece and thought one Clinton meant the other. It was Hillary who said this, not Bill. My bad, although it kind of makes my point for me.)
