Adam Serwer observes:

Just about the only Republican presidential candidate who hasn’t said anything ridiculous in the last 24 hours is Mitt Romney. It’s a low bar to clear, but for a candidate who obviously has his eyes on winning the general election and not just the Republican primary, it’s also something of a vindication. And, hey, it might work even in the primary: If Romney can stand by while his opponents implode — without getting drawn into the whackiness himself — enough GOP primary voters just may decide he’s the last electable candidate standing.
