I'm not going to claim that CNN was obligated to carry a speech by a former vice president currently not directly involved in politics. But I do think responsible news organizations should ask themselves if there's actually any way that a prominent Democrat could get a full speech aired live on their networks, especially given the fact that they've run Bush's stock speech in full about 700 times.
I remember when CNN used to run Newt Gingrich's morning press conferences every day. That didn't seem too unreasonable to me, actually, fairminded person that I am. And, yes, Gingrich was in the majority at the time. But is there no way for the minority to ever have a few moments to get their message out?
