I have not spent enough time reading their stuff, but the site Unity08 is trying to front a viable 3rd party via the web.
The requirements, as I understand them, are that the ticket (Pres. and VP) must either be non-politicians or a split ticket (Dem Pres., Rep VP OR vice-versa, and I assume (I) is ok).
It is a great idea, though I don’t know how well it will work.
I say Mitt Romney and Clinton. When they touch it would be like matter and anti-matter. The energy created in their annihilation could power the world for decades!!!
