realifedad saidCuriousJ I sure hope as you say, that some independent comes forward and shakes the hell out of this f'd up system we've got. and not some Tbaggin nut either.
The only type of viable candidate would come from the Tea Party or with similar roots. The issue is that as an independent movement, there are none others with the force and fury (and funding). Even if you're right about the Tea Party being funded by the old conservative apparatchiks (even if they support such things as gay marriage, against the Patriot act, pro legalization of drugs), there aren't any other movements really organized enough (and I use the term loosely) to get registered.
Tea Party movement candidates however have been cannibalizing establishment Republicans particularly at state level races - and that's something to watch. If they don't get the results they want (and by any metric, even the largest proposed cuts are measly relative to projected deficits), that makes a third party far more likely and popular.
