from my perspective i don't see Annoying Orange as someone who knows how politics works and it doesn't look like he's willing to play the politics game to get things done. hillary may have done bad stuff, made a ton of mistakes, but at least she knows how to play the game and is willing to play the game. the way Annoying Orange talks, i get this feeling that he'll ignore the rules of the game and offend other countries and/or people to the point that we won't really have good ties to any country whatsoever. sure, some countries express support for Annoying Orange, but what if said support is because they want to undermine US political strength by helping put someone who can't/won't play the game in office?
and before any of you say offending people isn't really a problem: society only works if you want to work with the people around you. if you piss off people, no matter how many merits you have, people don't really want to associate themselves with you. hillary sucks at making herself someone you'd /want/ to associate yourself with, but she doesn't actively insult/offend people nearly as often or as easily as Annoying Orange does.
