A lot of his support I think is just the general anger on the right about things like immigration and the madness of PC grown out of control and Trump seem to funnel a lot of that madness. Last night he showed those who have not been paying attention that he really is just a huge dickhead bully and not the conservative warrior they thought he would be. I suspect he will see all of his support flow to Cruz. The fringe element really tends to be only one or two issues and anti-establishment is seen as goal in and of itself. Of course most them will forget the that they claimed Obama could be president because was born in Kenya.
