I think the Atlantic said it better than I ever could.
"Donald Trump, on the other hand, has no record of public service and no qualifications for public office. His affect is that of an infomercial huckster; he traffics in conspiracy theories and racist invective; he is appallingly sexist; he is erratic, secretive, and xenophobic; he expresses admiration for authoritarian rulers, and evinces authoritarian tendencies himself. He is easily goaded, a poor quality for someone seeking control of America’s nuclear arsenal. He is an enemy of fact-based discourse; he is ignorant of, and indifferent to, the Constitution; he appears not to read."http://www.politifact.com/truth-o-meter/...-still-no-ther/
