Noonan is a freakin' airhead. She's like David Frum, she fancies herself Reagan's brain because he used to read her words in his speeches. Frum made the same claims about GWB, that all brilliant thoughts were really Frum's. Noonan's been riding this hobby horse for decades now because it feeds the narrative that Reagan was a moron who's only good attribute was his speech writers.
Of all political commentators, I rank her very near the bottom, way down in Paul Krugman territory. Calling her a POS would be an insult to POSs everywhere.
