David Plouffe seems to confirm what a lot of us suspected during last summer's VP deliberations: that Barack Obama wouldn't pick Hillary Clinton because he couldn't figure out how to make a former President named Bill part of his White House family ABC News' Teddy Davis has more: Obama campaign manager David Plouffe writes in his forthcoming book about the 2008 race that the future president was “clearly thinking more seriously” about picking Hillary Clinton as his running mate than Plouffe or advisor David Axelrod realized. Plouffe’s book suggests, however, that former President Bill Clinton sunk Hillary’s chances. “I still think Hillary has a lot of what I am looking for in a VP,” Obama is quoted as telling Plouffe and Axelrod during a meeting on the VP selection process. “Smarts, discipline, steadfastness.” Obama then adds, however: “I think Bill may be too big a complication. If I picked her, my concern is that there would be more than two of us in the relationship.” Thanks to The Bill Factor, Hillary, who was on the final list of six possible running mates, did not make the final list of three. The book confirms, as reported at the time, that the three finalists were: Sen. Evan Bayh, D-Ind., Virginia Gov. Tim Kaine (D), and eventual choice Sen. Joe Biden, D-Del. Plouffe’s book, “The Audacity to Win,” is set to be published on Nov. 3. TIME is running a lengthy excerpt in Friday’s magazine. It can be previewed HERE.
