Nobody felt especially zinged last night, but you can imagine that Barack Obama walked away from the first presidential debate of the season at least a little tingly, given the thrashing he took from Mitt Romney. Both candidates underwent a weird sort of position switching: Romney seemed during the debate proper—during the humanesque back-and-forth of it—to be comfortable and articulate, saving his beady-eyed-creep routine for the closing statements. His zingiest showing, “Mr. President, Mr. President, you’re entitled as the president to your own airplane and to your own house, but not to your own facts,” was an adaptation of the old Daniel Patrick Moynihan line, but updated for the modern era, when the man challenging the incumbent is a private-equity CEO irked that, of the two, he owns the smaller airplane.
