Politics | O: A Presidential Novel And the Author of O: A Presidential Novel Is... ...Mark Salter!

Page Six had previously guessed Salter could be the author, and there were some hints, writes Mark Halperin: Salter “has been holed up in Maine,” publisher Jonathan Karp had previously worked with Salter (and the descriptions he gave of the author matched Salter), there’s a story in the book that only a McCain campaign insider could have known, and “Salter's non-denial denial was the closest to a confession of any suspect who was publicly asked.” Click for a review of the book.
