Unfortunately, the 3rd parties so far have shown that they have no real capability to get their message out, or put candidates up who are as unqualified as Trump.  Jill Stein and Gary Johnson were both a sad joke.  Stein is an anti-vaxxer who just seemed to be in it to get some money.  Johnson, while I get that the libertarians want to be pretty isolationist, still couldn't talk about anything in relation to what is going on in the outside world.  

I have suggested again and again that the 3rd parties need to concentrate on winning local and state elections, then move to winning Senate and House seats.  This idea that a complete outsider can show up, win, and be effective isn't realistic.  Even if they could win, with no support in the House and Senate, they would get less done than Obama did in his last 2 years.
