Reason #879 that Meet The Press has become a joke:

[Sunday]was Gingrich’s fifth appearance on “MTP” just this year. In fact, Newt Gingrich, despite not having held any position in government for over a decade, was the single most frequent guest on “Meet the Press” in 2009 of any political figure in the United States. Literally.

... because when you want to have a serious discussion on the issues of the day, who better to have on than an extreme partisan whose only interest is to parrot talking points? Which actually wouldn't be such a bad thing if David Gregory ever bothered to challenge the garbage that's being peddled.
