Limbaugh nor Levin supported DJT's campaign until the final hour. Keep that in mind.
Rush supported Trump all along, and extremely effectively.
He is continuing to do so now.
Some people did not understand his methods, of often explaining Trump’s actions. I know, because I tried to point this out many times on FR.
In other words, if you were not a regular listener, and just heard the whining on FR ... then it is understandable how you would not have realized this.
BTW, TODAY Rush is walking it back, as I predicted Friday. He just completed an exposition of how Trump may have outwitted the Rats AGAIN. (Using M to build wall.)
