Actually the original would-be publisher, Poseidon, never got squat for their $. Obama choomed it all away w nothing to show for it at all—not even a chapter. His indefatigable agent when to a different publisher and got him a second advance. [You have to add the two advances up to reach the $165,000 figure, incidentally.]
When Obama looked as if he would exhaust the second pile of $, Michelle gathered up all his notes and dumped them on Ayers. This account may be found in a sympathetic book about the Obamas’ marriage by Jodi Kantor entitled, “The Obamas”. Kantor never interviewed the Obamas themselves, but did intensive interviews w friends and aquaintances, fwiw.
It’s worth a lot! Thanks. I thought that I remembered reading somewhere that Michelle admitted giving the notes to Ayers, but didn’t remember the source. Jodi Kantor’s book.
