Matthew 5:17-18 KJV
"17 Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.
18 A good tree cannot bring forth evil fruit, neither can a corrupt tree bring for good fruit."
A two-party system doesn't yield very much good fruit so what can we infer about the character of a two-party system? Sure parties have the right of freedom of association, I'll vigorously defend that. However as readers here are intimately aware, the two-party system has taken upon itself to act as a publicly funded 'establishment' filter in the conduct of our elections. The bottom line is that arrangement is not yielding good fruit. By postulation, a two-party system as it exists now cannot ever yield good fruit.
