David Plouffe
From 'The Audacity to Win'

In a new memoir, 'The Audacity to Win,' David Plouffe, who managed Barack Obama's 2008 race for the White House, provides a behind-the-scenes glimpse inside the campaign. Here's an excerpt:

Agony. Ecstasy.

The [Rev. Jeremiah] Wright story broke on a Wednesday and exploded across the media landscape the next day. We decided Obama had to take questions about [his former pastor's inflammatory sermons] head-on on Friday, in a series of lengthy national cable interviews.

There was one not-so-minor complication. He was already scheduled to do editorial boards that Friday afternoon with both Chicago papers about [real estate developer and political fundraiser] Tony Rezko, two hours each, no holds barred. Given no choice but to address Wright as soon as possible, we decided we would do a round of TV interviews on him directly after the Rezko boards. It shaped into quite a day, like having your legs amputated in the morning and your arms at night. The question was whether we would still have a heartbeat at the end of the day.

It was chaos and, quite frankly, frightening. I felt as if the wheels could easily spin off our whole venture. Still, Obama was the pillar of reassurance. "Don't worry, guys," he told us while making some notes on a stack of pages. "I can do more than one thing at a time. We are taking the trash out today. It won't be fun, but we'll be stronger for it."
