I think most all feel the same.
Speaking for myself, Levin came around initially to save his cratered bottom line. There was at least one story on the negative financial impact he suffered and loss of sponsors, over his opposition to Trump and Constitution flogging for Cruz.
He is wordy enough to adapt, to easily translate that financial reversal into a Recovery, with his emerging support of Trump.
You said it very well.. that we “can’t unknow” what we know.
I was never a Levin fan. Listened to a couple of his "get off the line, you big dope!" radio shows, & it wasn't my type of show. Levin, Coulter, Shapiro, Beck, fill in a bunch of other names, shape their opinions to get them profit. I'll listen to Levin, but yeah, his neverTrumper background isn't forgotten.
Cruz couldn't have beaten Hillary, but he made a huge tactical error tying himself to Beck, especially after Beck did that face in the Cheetos thing.
Trump is the only guy I trust 100% right now, aside from the Lord.
Its the same thing with Ann Coulter. I don’t think SHE likes this “populism crap” very well either.
