I haven't found a politician terribly inspiring in some time. Perhaps I've just become cynical and jaded, but as far as politicians go I like Romney quite a bit. He's not my ideal libertarian by any stretch, but he's a well-mannered pragmatist who doesn't seem to view political ideology too dogmatically. That's a big deal because he seems to understand how the economy works and has the intelligence & flexibility to handle situations as they arise with a measured & reasoned approach rather than a massive knee-jerk reaction based in some theoretical ideal.
Personally I'd have preferred Rudy (but only if he promised never to again say "Sadam Hussein WAS a weapon of mass destruction") but I'm pretty happy with Romney as a candidate. He's far preferable to Newt, the sweater vest, John McCain, and the clueless tool currently occupying the office.
