As it stands, I'm confident that Hillary's leads in the polls will translate into a win on election day. But if Annoying Orange were to be elected president, I'm not gonna shout doomsday or anything like that. The worst part of his being elected will be the fact that so many uneducated voters rallied so strongly behind all of his bullstuff. The second worst part of his administration will be whatever crazy forget he chooses to replace Scalia.
I'm sure that a Annoying Orange presidency would (or will) suck for a large number of reasons, but simple checks and balances mean that there's only so much harm the guy can do to our country.
