I'm a member of the Green Party. I'll fight you!
But seriously, I'm not stupid enough to vote for the Green presidential or national candidates because I know that's not how one-dimensional two-party splitting can be broken through, especially in the US's sytemically corrupt electoral system. I vote for Democrats more often than Greens, Libertarians or Peace & Freedom. And I have never nor will ever vote for a Republican. I believe GOP shouldn't be allowed on ballots.
Also, yeah, the Green parties in other countries aren't infected with American political woo and derp.
