When the chips were down and the alternative to the debt-ceiling deal was default, Mitt Romney, the one Republican running who might actually get the nomination (unlike Huntsman) and might seem like a plausible President (unlike Bachmann or Perry), came out against it. That should play well in Iowa. But in November? Not so much. The voters didn’t like the deal, but demanding a vote for default was a classically un-serious thing to do.
