" As a candidate, the president ordered a private security detail to clear opponents from rallies, but also encouraged the audience itself to remove people who expressed different opinions. A protestor would first be greeted with boos, then with frenetic cries of “USA,” and then be forced to leave the rally. At one campaign rally the candidate said, “There’s a remnant left over. Maybe get the remnant out. Get the remnant out.” The crowd, taking its cue, then tried to root out other people who might be dissenters, all the while crying “USA.” The candidate interjected: “Isn’t this more fun than a regular boring rally? To me, it’s fun.” This kind of mob violence was meant to transform the political atmosphere, and it did. "
