What's missing here, IMO, is a party. Who's with him? Do you have defectors from the 2 parties? Independents or popular figures joining up? Candidates being stood? A political party is not a manifesto, it's an organisation. I actually think there's room for a party to start gaining ground in the US. There are so many elected offices that the surface area is huge. Great for "guerilla tactics." IE, earning easy victori…
A political party in the USA needs an engaged, interested, reliable representative for every single county election commission, at the very least. The Libertarians don't have that. The Greens never bothered with rural areas. The Perot believers and the Tea Parties had boots enough but no co-ordination.
Facing a behemoth like the two parties head-on is impossible. You can't have as much coverage as them as a starting point. OTOH, you also don't have to stay in their paradigm or split your efforts so widely. OTOH, elect three senators or nine mayors would, in itself, represent a major victory and real political power.
