Both Hillary and Trump could really mess up free trade this time around. I don't trust either of them. They are both crooked and triggerhappy. Vote for the Gary Johnson the pothead, because character matters.
I agree I can see either Hillary or Trump tanking the U.S. economy and affecting the global markets big time. I don't trust either of them, either :-(
And about pot? I like pot. I haven't done pot since college, but I don't think it should be criminalized as it currently is.
Libertarians aren't all alike, and there's a big left to right spectrum from anarcho-syndicalists like Chomsky to anarcho-capitalists like the Tea(bagging) Partiers.
I believe a large part of the current political arena problem is that the majority of the U.S. electorate is largely suffering from global illiteracy--they are globally myopic. They have little clue what is really going on around the world, and even less interest in finding out.
