Just have a look at Ms. Stein's web site and when you stop laughing (or shuddering) it's easy to see why 3rd party candidates have had little chance of being elected. While moderate candidates usually do poorly, the most extreme ones are labeled as whack jobs and are completely ignored by the media.
Hillary is a criminal and needs to be in prison, not the White House. Donald is way over the top and should do more thinking before engaging the vocal cords. The rest of the US Federal government are criminals, so having a Clinton back in charge is a recipe for business as usual. With Trump, the House and Senate may have to spend considerable amounts of time nullifying his more outrageous antics that they won't have time to do as much damage. Trump is far from ideal, but not being a career politician, some common sense (such as it is) might be put back into running the USA.
