I’ve heard Mark speak highly of Rubio, on his show.
Here are a couple of articles where he seems to like Rubio...

Levin: Cruz, Paul, Rubio Among Best Young Conservatives Since Reagan

Is he (Levin) against Rubio, now..now that he seems to be endorsing CRuz and since Rubio dissed Mark’s CR forum? Not sure.
Levin is a straight shooter.
