What the heck happened to Cokie Roberts?!?!?!Yesterday I heard her respond to a question about the sorry state of political discourse by citing talk radio (she was on a local "public" station) and late night liberal comedians.(Rush who. . .? ) A year or so ago she and her husband were critcizing workers at Walmart for trying to unionize! It's hard to believe that she was part of a radio/tv network that brought down Richard Nixon. I'm not buying her book. If I want information I'll tune into Air America.
