It's kind of sad to see so many people afraid to say that they are voting for an independent who is not a hasn't been  puppet slave to the party, because they themselves  are a puppet slave to the party. To those, it's only a career to them...it's not a principled  calling nor is it really to make things better.  
It's also sad to see Americans who are so confused when an independent makes it this far without party backing and is not a puppet to the corruption and hasn't ended up selling out or being bullied out (Sanders) who  surprised the established parties who were so sure that their chosen front runners would win.  People are so used to the same way every election because it is so planned and established that they can't deal with any surprises . So when both corrupt parties start pulling together  to try to attack the independents, some people can't see that both political parties are corrupt.  Had it been Sanders that hadn't sold out they would be doing the same to him
