If you're going to be a leader of the free world; enforcing rules, making big decisions and speaking directly to and for the people, you gotta look the part. If people can't look at you and think "that guy seems like he can make a few decent decisions for me and my peoples," than you certainly won't be given the benefit of the doubt.
