Trump supporters will brook no criticism of their man. The fact that Cruz was so much smarter than Trump about the delegate process and now is behind the curve makes them lash out angrily. Trump even hired a seasoned political operative who worked for Romney but that is okay. Of course Manafort is connected to the odious Roger Stone who still manages the sleaze behind the scenes. But that is okay, too.
Reminds me of the mass hypnosis and blind allegiance for the current cult of personality who occupies the WH.
