Unfortunately, I think the Iowa caucuses have set back alternative voting schemes 100 years. No one will trust them. They will just think it is a Trump or Clinton affiliated company writing the code to fix the outcome.
A return to federalism, with stronger states and a weaker national government, is easier to achieve than a third party...and that would result in less money at the national level. I know Chris thinks there is more corruption at the state level, but I think that is just because he lives in Louisiana.
Of course, as I say this, we are facing economic threat from China...and I'm not sure 50 states can win against China. It's quite a conundrum.
