Hmmmmmmmmmm
Isn't gossip vicious! ...and fun. Just between you and me, I would take a guess at Ken Khachigian as the Hack, he is a former Nixon and Reagan speechwriter who is essentially a political consultant in California. From what I have seen of him, he appears inarticulate [see his October 03 interview with Brit Hume on the Arnold sex disclosures by the LA Times--google his name and it will come up fairly quickly] and greasy. But I really don't know. I only say this as names that could be ruled out or in with further info.
And though I have only heard good things about Peter Robinson who is credited with "tear down this wall" speech, he may be the haircut. He did write two books, How RR changed my life" and another about his struggles in the GOP. I haven't read either one, but if Peggy felt that he should have given credit to Bently when talking about how RR changed his life, that may be it. Also he was a speechwriter from 82 to 88. The only rule out clue is that the Berlin Wall speech was in 87 not 88, so it may not be him, or else she is giving [mildly] disinformational clues. Who knows?
Boy, that was a zinger about the Hack. I guess Peggy is not inviting him to her next party.
I agree that Robinson could be The Haircut.
I think Darman could be the Hack.
I thought the last section of this essay was gratuitous, unnecessary and totally beneath Peggy Noonan.
