As politician and president, consider his recent claim that Obama failed to call the families of fallen soldiers; his focus on whether professional football players are standing for the national anthem, combined with a threat to revoke the NFL's tax exemption; his ad hominem attacks on the Republican establishment; his suggestion that if broadcasters persist in offering "fake news," their licenses might be revoked; his contention that Democrats do not believe in, and want to abolish, the Second Amendment; his renewed emphasis on the importance of saying "Merry Christmas"; his continuing focus on Hillary Clinton and her supposed crimes.
