Greg Mankiw is the the closest thing to a "rational right" person I know of. He's "close" because he once worked for Vlad Bush and because he's a Libertarian, which I think sort of qualifies as sort of on the right. (Would he work for Vlad again? He doesn't say these days.)
The Pigou Club is where he meets people like Al Gore and Paul Krugman. Follow the wikipedia link to get the background.
