I believe it. I once ran for office locally with no political experience on a wishful "average guy" ticket (I lost badly), and one of the hardest things about the process was taking criticism from people who didn't know me, who just wanted to vent their anger at the system or in some cases, trolling from the incumbent. It dawned on me pretty quickly during the race that the kind of person cut out to win and rise in this line of work has got to have skin as thick as rawhide, and a psychopath's inherent disregard for other people's opinions and grandiose sense of self would really fit the bill.
