Catching on

I don't know why, but the perception of Obama's rhetorical greatness has stuck in my craw for a while now. The BBC's Justin Webb notes from the G20 summit:
But other than that, I felt it was not Obama's finest hour - he was slightly tetchy with an American who asked a question (he wanted it to be locals) and staggeringly long-winded in his answers. Oddly, he seems more charming sometimes when that is not his principal aim.

He's just not that great a public speaker.
