Looking at the Republican nominees, Josh Marshall would prefer Romney to Giuliani
I know I've said before that Romney's profound and almost incalculable phoniness is a terrifying prospect to behold in a possible president. But the danger of phoniness, aesthetic or otherwise, cannot hold a candle to the truly catastrophic foreign policy Giuliani would likely pursue if he got anywhere near the Oval Office. Watching him campaign it's pretty clear that the guy has no real sense that posturing and pandering to ethnic paranoia in New York City simply isn't the same as running a national foreign policy. The people he's coalescing around himself as his foreign policy advisors are the ones who are going to help him learn as he goes. And they are simply the most dangerous, deranged and deluded folks you can find in American political and foreign policy circles today. It's really not an exaggeration. Scrape the bottom of the "Global War on Terror" Islamofascism nutbasket and you find they've pretty much all signed on as Rudy advisors.
From what I know of Giuliani's rhetoric and the resumes of his foreign policy advisers, I agree. A panderer is always better than an egomaniac. A panderer can be influenced. (It'll be so fun to watch Romney desperately tack back to the center if he gets the nomination.)
