I think the hottest fire Trump has tapped into is the arrogant, self-important and entitled GOPe and their talking head shills, including Luntz, on Fox and other media outlets. Those folks have steam coming out of their ears and fire coming out of their eyes, and, ... wherever.
Yeah... the fact is that most FOX watchers are realizing (even the slow old ones are realizing) that Krauthamer, Will, Luntz, Rove etal are just shills who have no reall knowledge of anything. They are just mouth pieces doing and saying what they are paid to say. They are clueless liars.
