No, they do support him and that’s why they give him all the publicity. Also, Trump, being an entertainer, knows how to stoke them. The serious politicians are more inept and also think that the voters are interested in ideas - which are of interest to nobody in the press or in the GOP voter base.
And the Dems obviously abandoned ideas long ago, electing the populist Obama because of his airy fairy promises. However, he was an officially Dem-sponsored populist, whereas there are still some in the GOP who would actually like to support a candidate with real ideas and not just a good media touch. We shall see...
They won't even pan the room with cameras to show the size of the crowds.
I think Joe Scarborough and Mika have begrudingly come to like Trump, but that's it.
BTW, all the candidates have been invited to call in to the various panel-styled shows and they won't do it (the Q & A's can be pretty tough).
