This letter shows that when Trump says one thing his detractors hear a different message than his supporters. Is Trump unclear or are one or both sides easily confused? Or is Trump a poor communicator?
I'll concede that Trump spoke specifically to criminals crossing the Mexican border crimes. But he lumped all Muslims together when he called for a: “total and complete shutdown of Muslims entering the United States”. That includes those who could come here legally. 
Dale's score: +1 and -1 or 0.
The second argument: "Kagan hears [leaders] who have created a wonderful government in total service to  [us]..." Kagan did not say that nor implied that government was in total service to us. Dale's score: -1
Lastly, Kagan never used the word "total" control. He said Trump needed mass support of a "strongman...the leader (Il Duce, Der Führer), in whom could be entrusted the fate of the nation."
Dale: -1 
So the question remains: Why do the two sides hear a different Trump and does it matter?
