JOURNALISM: CBS’s Bob Schieffer to Guest: You Shouldn’t Be On a News Program, You’re Controversial and Divisive! “After Walter Cronkite left CBS, he started speaking for up for increasingly nutty causes, such as “One World Government.” When Dan Rather left, Mr. Objectivity began hosting fundraisers for the far-left Nation magazine. Bob Schieffer is set to retire this summer; based on the track record of his former CBS colleagues, his columns and speeches after he’s free to go full Bullworth should be loads of fun to read.” It’s like they’re undercover lefty operatives, until they’re not undercover any more.
