Nothing "whacky" about it. The two parties colluded extensively after Perot to prevent 3rd parties from gaining traction. It is quite deliberate and intentional. There are reasons why a Congress with a 9% approval rating regularly has over 93% of incumbents re-elected.
I did not refer to it as "wacky" and agreed with it. I did say it needs to be fleshed out, and it does. That's among the things I tried to do.
