Oh Yes. Trump uses immigration in much the same manner Joseph McCarthy used Communism in the 50's, knowing full well there is enough ignorant and paranoid people who can be manipulated by this propaganda. It's not surprising Trump does so well with the undereducated, just as the snake oil salesmen and holy roller tent revivalists do with the same group.
P.S. At least Joseph McCarthy was man enough to join the Marine Corps. and serve his country in that capacity. Donald Trump is a draft dodging coward
