I called Professor Don Foster, of “Primary Colors” fame. He outed Joe Klein. He doesn’t want to do it. We also discussed various reasons for not doing it, not much time, no significant evidence of this allegation, and he usually works on court cases. Also, other problems such as: need pure writing from Ayers, w/o corrections and maybe original manuscripts of Obama’s “memoirs”, and finally maybe its not such a good use of resources as he may not be able to say definitively that it was ghost written.
So that’s one no, only a few more till we get to a yes.
It doesn’t seem like this project is possible in the time available, judging from the Primary Colors case. A simple denial would last Obama/Ayers many months.
