“He got on board before 2016.”
lol. That’s certainly one of the more foolish attempts to rewrite history. You could actually learn by simply using a search engine instead of your faulty memory.
“Mark Levin: I won’t back Trump in the general

“Some point you’ve got to stand up to it … I do not like bullies and I never have,” Levin said before adding that if the (Trump) campaign and its associates anger him again he will try his best to get supporters to abandon him.
“If they piss me off one more time, I’m going to urge millions and millions of you, should he get the nomination, not to vote for him either,” he said.
Note the 04/08/2016. History didn't stop in April. :-) In September Levin said, "I’m gonna vote for Donald Trump." [The Hill] I'd predicted that he would earlier (I believe in a post on this forum). At first he did so begrudgingly, saying, "I take no responsibility for the dumb things he says or the dumb things his surrogates say."
Between then and the election, though, he went into more detail in supporting Trump, and went into full attack mode against Hillary.
