That's what your TV wants you to believe, Ron, because it sells advertising. Many of my friends on the left have your same blind spot of thinking they are too intelligent to be manipulated. Just like Fox making mountains out of AOC's porly conceived molehills, so CNN does with Trump. The boogeyman puts butts in seats.
But If you take the time to have reasonable discourse with people who have different views than you (vs slinging shlt at each other on a messageboard), you'll find that you probably have a lot more in common than you think (or care to admit).
