It's asinine authoritarians like you who are the main cause of grief in the major parties; you are intolerant of disagreement."Third party" is a useless term, Oom. It could be to the right of the republicans, the left of the democrats [like me], some weenie position in the middle, or some one-issue lunatic group..
One of the two major party nominees is definitely going to win, but the truculent "third party" voters might help the less wanted of the two to win.
To you, that's OK. To me, it isn't. That's all to which it comes down, really.
