Have you heard of Americans Elect?
I heard about this from an op ed by Michael Eisner (http://www.latimes.com/news/opinion/commentary/la-oe-eisner-americans-elect-20120320,0,4438046.story)
Their goal seems to be to have a nation-wide nomination of a presidential candidate in June who shows up on all states' ballots in November. The individual chosen will then be asked to choose a running mate of a party other than their own. Is this a way for those of us in the middle to grab some power back from the extremes who thrive in the traditional 2 party primaries?
