I dont listen to Levin religiously , I didnt see it that way(never Trumper) I think Levins skepticism about Trump was exaggerated by some , I just remember Levin saying Trump is a Populist, not a conservative then after Trump won the primary Levin said he would back him IIRC pretty much same with Rush
Palin is great, she really got attacked worse than Trump, even a lot of people on the right took the propaganda bait, shes not perfect and neither is Trump.....or Levin.....(or myself)
Even after he sort of endorsed Trump he always had a complaint. I am very pleased with his position today.
I have listened to Rush for 29 years and I can tell you that he was not a Trump supporter in the beginning. He did point out what Trump was doing right, I think, in the hopes that Rubio or Cruz would pick up on his method.
When Trump supporters called in he called them Trump-pests with a flourish and if you were a 24/7 subscriber you could see the hand waving and facial gestures when talking to some of them. Once the outcome was clear he became a full Trumper. Truthfully Rush never endorses until after the Primary is over.
