Larison, like the Dish, sees a real shift:
When I described a shift in conservative attitudes towards military intervention a few weeks ago, I wasn’t arguing that the shift was huge, but I would insist that it is significant.
I was careful not to make extremely broad claims that this proves that the GOP is undergoing a massive shift on foreign policy, much less that it is going to be reliably non-interventionist or antiwar in the future, but there is some real movement going on. It is important to emphasize that the actual antiwar votes for the Kucinich resolution in the House represented a minority of Republicans, and the most vocal opponents of the Libyan war among the 2012 candidates are generally considered second-tier or long-shot candidates. Even so, the number of antiwar votes was remarkably high, and the number of candidates opposed to the Libyan war is much greater than anything we’ve seen in the past. Republican and conservative opinion on military intervention has never been monolithic, but until recently skeptics and opponents of such policies have been almost completely unrepresented in Congress and in presidential debates.
