In recent days, Trump has sneered at the looks of a woman who accuses him of sexual assault, denigrated the appearance of Hillary Clinton, proposed to drug-test his opponent, used his campaign to promote what appears to be a Russian covert operation, asserted that Clinton has held secret meetings with international bankers “to plot the destruction of U.S. sovereignty,” attacked “Saturday Night Live,” promised to jail his opponent and contended that the “whole election is being rigged.”
