The best metaphor we can come up with for Mitt Romney is that he reminds us of Linda Blair in the "Exorcist" movie. Remember that scene when her head rotates all the way round like it's not attached to anything?

Well, that's Romney. With almost any issue he seems able to rotate his head around until he's seen it from all 360 degrees – and made solemn pronouncements about it, often diametrically opposed. In this, ironically enough, he is kind of the anti-Ron Paul.

Ron Paul, of course, is the libertarian-conservative presidential candidate and Republican Congressman from Texas who is famous for never compromising.

As a firm believer in the free market and competitive money, Ron Paul has been a critic of central banking for most if not all of his adult life. For decades as an increasingly successful politician, he was one of a very few who consistently espoused abolishing the US Federal Reserve.
