I hear you, I do. Jill Stein is not a perfect candidate by any stretch. She's made several odd comments recently that shows she's a little out there...most notably the crap about how wi-fi might hurt children or some shit. BUT, she is almost in lockstep with my political views, as is the Green Party as a whole. The Democratic Party under Hillary is as status quo as it can get. That works for you. It doesn't for me. I think we need fundamental disruptions to the typical approach to our foreign & economic policy.
Furthermore, I don't actually think Jill Stein is going to somehow go from polling at 3% to taking the electoral college. My support for the Green Party is a protest vote, by on the policital side of the fence that I'm actually on. Gary Johnson seems like a great guy & much more sane and realistic about how govern than Ron Paul, but the Libertarian Party still comes out looking like looney tunes to me on a lot of their stances. Yeah, let's just dissolve both DOE's ( believe they wanna get rid of the Dept of Energy in addition to the Dept of Education), the EPA, the Fed & turn back to the gold standard unilaterally regardless of what the rest of the modern economic world is doing. That'll be great for the country! I'd still rather have him as president than Trump or Clinton, but I cannot vote for such a far right party just b/c they align with me on social issues.
And like I said earlier, to get the Green Party to actually have a real chance down the line required a steady, growing presence in every successive election, both from a perception standpoint & also from the very real federal matching funds they (and any third party) can amass if they meet certain thresholds in elections. Only way for that to happen is to vote for them and try to create a movement on the left similar to what my man Bernie just did. Bernie's out, but I'll go with the next best thing.
