Sen. John McCain will not be a guest on Meet the Press on Sunday. Please do not be alarmed; this happens now and then and you can rest assured he will return soon.

On the other hand, it also appears that Sen. Lindsay Graham will be a guest on CNN but without being accompanied by either McCain or Sen. Joe Lieberman. Both events taken together might suggest a possible change in the TV talking head universe.

What old and uninfluential political figures will provide outdated conventional wisdom and be coddled by inept anchors as they ride their same old hobbyhorses going forward?
