I don’t know about Levin or Shapiro or others like them (Bill Kristol for instance) being derps; I suspect they are wedded to certain ideologies and beliefs which they are loathe to give up. Why? Because they’d have to admit “I was wrong”, and people with inflated self esteem hate to admit they were ever wrong.
A person interested more in truth than anything else doesn’t mind admitting they were wrong; in fact, they thirst after truth.
Some may be monetarily influenced as well in various ways.
Very succinct .
I believe there was evidence a while back that Kristol is or has been “playing for the other team” during the election and after. Ties to Hillary.
Also(!) It has to be considered that many of the people who are so furious are furious because they have something to lose!
Some just really really liked Cruz too - I think Levin’s daughter was on the Cruz team. I think they are partially mollified as we on the right honor the man as a senator, though as president, not so much.
