I understand. I am a leftist though. I was never going to vote for HRC to begin with. I never even voted for Obama. Just because I'm a leftist doesn't mean the Democrats are entitled to me vote.
Here's the thing: If you're that far out there to the left, then both major parties seem to show up only in your rear-view mirror. I get that. But I also get that:
A. The Green party has never been battle-tested. We can go back and forth on the Greens' platform and whether it would work, but the truth is that because they've never had the reigns of power--hell, they don't even have a single seat in Congress or even a state legislature--we would just be theorycrafting.
B. Because of districting and first-past-the-post elections, entry into the political sphere for minor parties is very difficult. Take your state of Michigan, for example. Republican Representatives got 2.243M (48.0%) of the votes, Democrats got 2.194M (47.0%) votes, leaving about 5% of the votes for third parties. It is also important to note that because of gerrymandering, the GOP took 9 seats and the Dems only got 5.
You want to know what will give the Greens and other minor parties a chance? Proportional voting. There are several ways to do it; I for one would like to see something like the
single transferable vote by party. That way, you could, for example, freely choose what party you wanted, and if you wanted to maximize your chances of having your vote count, rank as many parties below the Greens as you saw fit.
But how to get past the issue of Congressional districts? Abolish them. Make the entire state of Michigan into one single superdistrict. You guys currently have 14 representatives, so to get a Green into congress, you would only need about 7% of the overall vote, which exceeds the 5% minimum that, say, Germany puts into place. As a bonus, no gerrymandering.
That kind of political reform is what's going to move us forward and empower parties such as the Greens. But simply sitting out elections because you don't like your limited choices? Nah, no good. That won't help anyone except the Republicans.
