I believe Levin has already taken Trump to task on social media.
As we’ve already seen, that will likely inspire the Trump-a-maniacs to diss Levin as a fake conservative who is involved in a conspiracy to bring down the one true American savior Trump.
Levin is indeed a clown. Want evidence? He's never reported any of this:

When Levin starts vetting the candidate he's pushing, and stops censoring his facebook or his calls for this stuff, then I'll take Levin as an honest person again.
