You have two options for POTUS, that's it. Doesn't matter how hard you want a third option, there's two. One is exponentially better than the other one. You can vote for the better option and give the world a better shot at a better future, you can vote for the worse option which is bad for everyone, or you can not vote or vote third party, which is bad for everyone unless you were going to vote for Trump in the first place.
Those are facts, no way around it. You can cast whatever vote you want from you high horse. There's only one benefitial option though. Help Trump and Russia, or help the rest of the world. There's no in-between. If that doesn't click with you, you must either lack empathy or have zero understanding of how the world works.
