Bill Moyers, if ever there was a stereotype of a limousine liberal, he is it.
Isn't Moyers the one who published a lie about Barry Goldwater during the 1964 campaign and then refused to apologize?
Fast fact: In his 1970 book Radical Chic and Mau-Mauing the Flak Catchers, Tom Wolfe came up with the term "limousine liberal" to describe then NYC Philharmonic Conductor Leonard Bernstein after Bernstein threw a party for the Black Panthers at his home.
So Bernstein is the prototypical limousine liberal, and, as you very rightly point out, Moyers is a stereotypical example of the species as it exists today.
