No it was Miller. The old SNL news guy and washout on MNF.
However, in thinking about it I may have overstated the case when I said:
I was quite surprised that he he has turned conservative
A more clear wording would have been:
I was surprised to hear him spouting his support of some conservative viewpoints. I am sure he is still very liberal in other areas.
And that's why he doesn't have a show anymore.
