Me, too. Us regular Sunday show viewers/critiquers need to start telling the networks that we're on to them regarding Biden, McCain, Hagel, Lugar, etc. We want fresh blood! And if they're going to have on a Republican, make sure it's a real one and not some old stammering, tottering RINO!
I do that, and assume I'm not alone. I'll often put the words To The Producer in the subject line, along with the comment, hoping they will pay attention to it more.
