It's a good sign.
I hope this'll serve as a lesson to the next "Ally" who makes a dick out of himself.
He did make an ass of himself, but that might not be at all related to CNN's decision to drop him. It might just be what they said--his ratings were low, and I have no idea whether his comments had anything to do with that.
He also might stay with CNN anyway, just not with his own show.
