I personally do not care if Mark has such people on his show.
A host is going to want to have guests from time to time.
I can’t see where it’s Mark’s fault that Rubio has earned so much dislike for himself.
That being said, I don’t have to listen to such guests if I do not want to, and I certainly do not have to vote for them.
Yeh its Levin’s show he can have on who he wants. That does not mean he’s going to endorse Marco.
