In the political landscape most voters don’t ooze passion about presidents, which is probably a healthy thing. Trump fanatics would likely insist that they have nothing in common with Obama fanatics, and vice versa. They frame their disagreements in terms of issues such as immigration, building a wall on the Mexican border and whether to admit Islamic refugees into the United States, but at the heart of the contempt is a combination hero worship and joyful excoriation of an opposing villain, pretty much what you’d observe watching the fans during a football game between the Chicago Bears and the Green Bay Packers.
