“aieeeeee,” sez un buen amigo, “el keith es un hombre con cojones gigantescos!” Yes, Keith Olbermann still sizzles. His latest special commentary, an exemplary piece of trash-tawkin’ disapproval, hews to the same high standard he set for himself here and here. It’s not just that he’s so good at delivering his epithets for the BananaRepublican-in-charge. Or that he’s doing it on mainstream TV, no less. But that all his epithets (“a pathological presidential liar” who is “transcendently stupid,” “an idiot-in-chief,” “a president manifestly unfit to serve”) have the ring of truth and a conviction behind them worth a thousand pictures. Especially when he looks straight into the camera and says in his closing remarks, “You, Mr. Bush, are a bald-faced liar.”
