Either not voting or voting for Hillary on a "lesser of two evils...I hope" basis.
Honestly, as a democrat both Hillary and Trump are despicable candidates to me, so at that point it's more on the grounds of which candidate I think will fuck up the country least. Trump was very much independent before he realized, at least as I saw it, that he had to play to the support of his party's most common denominator; the fearmongering and the traditionalist. He knew that this wouldn't break the opinion of the younger audiences while also gaining the support of the older, because frankly the younger people voting for him aren't necessarily voting for his policies at all and they may not even realize it. They're voting for a celebrity name.
Hillary has policies that line up more with mine though, and I don't necessarily think she'll piss off our allies or ruin trade with other countries. Trump will undoubtedly have enemies on the inside and outside of the country, whereas Hillary with have none; her time in office will be plain and sterile. But we can't ignore facts and frankly Hillary is a nightmare when it comes to hard facts; she jumps on popular opinion bandwagons, she lies and downplays and she also has admitted to repeatedly making mistakes on matters and changing her views later.
And yes, I know, someone's opinion changing as time goes on isn't something to crucify a person for...but should we not expect far more out of a president than a current-rider? Bernie was supporting rights for essentially everyone back when an opinion like that gained him no friends, and many enemies. Go take a cursory look at his past; he's been a trendsetter his entire life in the political field and even predicted the outcome of the US's war on the middle east perfectly. Hillary represents perfectly why Bernie was so notable; they represent the difference between someone who thinks about what is right and best for the people they govern, and what will get them the most support among their peers. Hillary is shady and underhanded and Bernie genuinely gives a shit about the people he has power over, regardless of who they are.
So in short...probably nobody, to be frank. They're both shit candidates and proved to me how much the US is floundering, and how masterfully the government somehow manages to put itself into this "lesser of two evils" spot at any cost. If nothing else comes out of this, whoever wins I'm pretty damn sure US citizens will have four years to consider how hard they fucked up if Trump is in office, but with Hillary I think she may come and go through an eight year term thoughtlessly, without any kind of change in our current course. So which is better? Safe sterility, or chaos? Because that's pretty much what the vote comes down to.
