It was 7:35 p.m. on an election night, '88 or '90. Moyers was posing as an "analyst" for CBS. (You can't make this stuff up.)
Very early returns had come in from a couple of southern/border states and they were trending Repbulican.
Moyers, clearly enraged, opined, "When you see the South voting Republican like this, that is racism."
He doesn't think he has a bias. CBS regards him as a suitable "analyst."
You can't make it up.
Mike Wallace of CBS even said something to the effect that he was liberally biased. When Wallace says that about you, well, that speaks volumes.
