Not to worry. In this media-driven age, the one who gets the biggest crowds wins. Obama got bigger crowds than Romney. Trump gets bigger crowds that anyone in history.
I recall George McGovern had enormous crowds in 1972.
Bernie Sanders also gets yuge crowds too, much bigger than HRC. But HRC gets more votes.
I would agree that DT has an enthusiastic following.
I would disagree that they are the majority of the overall US electorate.
Trump brought Jeb’s likability down to zero in a few months with Jeb spending millions defending himself.. he can easily bring HRC down a few notches by Nov
