From a New York Times profile on quotes Obama:

“I love when I’m shaking hands on a rope line and”— he mimes the motion, hand over hand — “I see little old white ladies and big burly black guys and Latino girls and all their hands are entwining. They’re feeding on each other as much as on me.”

He shrugs; it’s that distancing eye of the author.

“It’s like I’m just the excuse.”

regardless of whether it’s put-on humility—there’s something in there to meditate on a bit, I think.
