Laurence Kotlifkoff, economics professor at Boston University (and my macro professor's advisor) is seeking the American's Elect nomination for president.
The difference between this and a large chunk of the Ron Paul people is that I know he can't win (and that it's because of more than just the elite media silencing him).
But the whole third party movement as a centrist force to be reckoned with has always been intriguing to me. It actually seems like a third party movement would do more good in Congress than in the presidency. Maybe Kotlikoff should go for that Massachusetts Senate seat instead.
