It almost makes me want to vote for him. If assholes like these can't stand him, then there must be something he's doing right. Or maybe it's because assholes tend to spend more time fighting each other than everybody else, which is why even with completely unethical tactics, they can't hold onto power for long.
Or it could be because he was the presumptive nominee, so they all ganged up on him to try to take him down.
