Interchangeable. However, Republicans and "conservatives" would be more likely to oppose warmongering and stupid/evil policies under Obama. And the public would be much more likely to blame liberalism or socialism for the country being in the toilet.. I don't think OWS' nonsense (or worse) would have as much of a chance of gaining a serious foothold in public opinion under him. So I guess Obama, if you held a gun to my head. Of course there's a small part of me that would be happy seeing him lose in an landslide to just about anyone.
Beyond Ron Paul, where is the Republican opposition to any kind of warmongering?
You had Bachmann & Co. opposing Libya, and relatively anti-warmongerish Donald Trump did lead in the polls at one point (admittedly not for that reason). Still not typical in the GOP, but non-warmongering ideas are much more popular within them than in '08.
That's mostly what I was getting at, but you had at least a few Republican politicians and talk radio hosts claiming to be anti-NDAA or SOPA or whatever. Does anyone see that happening under Romney? I honestly think the best chance (however slim it is) for this country to regain some sanity is for us to hit rock bottom under Obama.
