Whether Mitt Romney wins or loses tonight (or tomorrow, or next week), the most interesting story of the campaign, to my mind, is his turn to the center starting in the first debate. It’s interesting first of all because it happened so late. After the primaries, most pundits expected Romney to Etch-a-Sketch his way to the center. Instead, he chose Paul Ryan and temporarily turned the race into a referendum on entitlement cuts. Conservatives loved it, until Romney began falling behind in the polls, at which point they began slamming to the press.
