Rush did take a few swipes at Trump in the primaries - I recall emailing him a few times. He seemed to be favoring Rubio or Cruz. Rush jumped on with the president later, as have many others.
I compare former anti-Trumpers to former smokers. They become some of the best advocates for their new positions because they see their error. IIRC, there are some very pro-Trump people who didn’t start out that way. Levin, Katie Pavlich, Greg Gutfeld, Greg Jarrett, so name a few. I would say Glenn Beck, but he’s still a little crazy and I think he cheered on that Republican Amash? who called for impeachment.
I don’t think Rush was anti-Trump as much as he was skeptical and came on board late.
Rush kept making the comment that he NEVER endorses anyone in the Primary.
But he definitely was more PRO some than he was Trump.
Rush taking swipes at Trump in 2016 was infuriating. I thought he got over it until I heard him on Friday. I’m not saying he’s going to swipe at him for second campaign, but I am not holding my breath. I’m feeling uneasy about Rush’s full commitment, he seemed to “apologize” for Trump’s *Trump* behavior. I think he’s frustrated a little that we expect him to be Trump’s spokesman. We don’t, we like listening to Trump directly.
