He’s divisive towards Levin because Levin is whipping his @$$ in the ratings. I knew when the day came and Levin was going toe to toe with WeinerNation in S.F., he’d go back to selling herbal medicines.
That's entirely untrue, let's try not to let our dislike for someone encourage us to 'bear false witness' against them.
Savage has it out primarily for Rush and O'Reilly, less so for Hannity, he never mentioned Levin until Levin got on the air and started attacking him in defense of his butt buddies, Hannity and Rush. He still rarely mentions Levin in relation to the others.
