I keep being called a liberal by people on this board, but I'm more likely to vote for the Libertarian over Hilary because I just want more parties in the game already. It could be the one chance to bring compromise back into the political process. Get L's their needed % to be taken seriously and next time maybe Greens or some other group gets their % and pretty soon the D's and R's have to figure their shit out. We can all benefit from that.
I like the idea of getting the next most popular third party enough support to get funding and participate in the debates. And I like a few of Gary Johnson's platforms, but his tax and social service positions are like polar opposite from where I stand, I don't really think I could vote for him. So probably going to vote for Jill Stein (who is pretty close to Bernie Sanders on most things and really big on electoral reform) even if she'll still be well behind the Libertarians.
Plus I like the idea of both a right-ish and left-ish minor party rising in tandem. Poses something of a united front while diminishing the spoiler argument.
There is no possibility of there being a third party in American Politics without major overhaul of the electoral process. It is not a matter of will, it is a matter of math. Our first past the bar system guarantees only two parties.
The best you can do is swap which two parties are in contention. If enough people decide to switch to the Libertarian party then the Democrats will win every election until the Libertarian and Republicans unite their forces either by people abandoning one of them or actually combining into a single party. Then what ever that new party is will have the ability to gain enough support to challenge the Dems again.
You are correct. But I think that having a temporary surge in third/fourth party popularity will make people more open to considering electoral reform, especially if those parties are strongly advocating it.
