Basically, the Tea Party needs to GET organized and raise a bunch of money. They need to be able to match the next Romney dollar-for-dollar in the next presidential primary. Problem though, who decides which candidate the organization backs? A vote of the membership that you're going to stick to even if it turns out to be Ron Paul?
I would wonder if it's even possible to get on the presidential ballot nationwide for a new party at this time. I think the Americans Elect party Schoen is running has been working for months to get on all the ballots. Bottom line, if an organization could be made that quickly, it would've been made in this primary to defeat Mitt months ago.
It could be done - but this organisation's supporters would have to spring forth from the soil like Cadmus' Thebans and get to work immediately!
