On Wednesday night, Tavis Smiley welcomed film director Errol Morris onto the set of his PBS program to talk about Morris’ new documentary on former Defense Secretary Donald Rumsfeld. Unlike Bill Maher, who challenged Morris when he interviewed him last Friday, Smiley joined Morris in maligning Rumsfeld throughout the entire interview.

Smiley seemed appalled that Rumsfeld ever came to be in charge of the Defense Department, and by extension managing the prosecution of the Iraq War. He remarked to Morris:



Bill Maher's weekly show on HBO is occasionally a pleasure to watch, at least to this conservative, because he's that rare liberal willing to turn sacred cows on the left into hamburger.

Last month, for example, he challenged MSNBC's Rachel Maddow for her network's obsessive with the Bridgegate scandal she clearly hopes will sideline New Jersey Gov. Chris Christie's prospects in 2016. A week earlier, Maher derided liberals from the 1930s for their love of Soviet dictator Joseph Stalin -- while Maher's predominantly left-leaning audience sat on their hands in response.
