What is behind the Trump juggernaut is plain ignorance. When ever some one asks Trump for specifics, he assumes the look of a deer in head lights.
The recent debate was quite educational in the degree to which the mediocre Rubio (genitalia jokes and human waste comments notwithstanding) and Cruz made Trump look stupid.
Now when he has to deal with Hillary (that is if she can fend off Bernie in the Midwest, where her black base will be of less help to her than it was in the South) Trump will look quite stupid. She describing what she will actually DO, having defined what the problem is. Trump screaming that Hillary is an old and ugly wench who he will never marry.
He will NOT be able to claim that she is dishonest, because Trump certainly isn't honest!
GOP fanatics will fall for Trump. The mainstream suburbanites will NOT fall for him, and in fact are already saying that they have no intention in voting for a buffoon who will reduce the USA into being a laughing stock.
