MADDOW: I also want to tell our viewers that we invited Senator Lieberman to come on the show tonight. His office did not even bother to respond to our requests.

But, Senator Lieberman, you should know you have an open invitation as you long have had to come on the show. I promise you will get a fair shake. Actually, at this point, I promise to not only buy you a shake. I will buy you a cookie if you come on the show.

We won't be seeing that happen any time soon. Lieberman won't get the kind of softball interview he received from Bob Schieffer if he comes on Maddow's show.
