Would candidate Obama approve of President Obama?

I had arranged to meet David Plouffe on Saturday afternoon at a Starbucks on Wisconsin Avenue in Washington. The night before, a copy of his new book, The Audacity to Win: The Inside Story and Lessons of Barack Obama's Historic Victory, was waiting for me when I checked into my hotel at midnight. I flipped it open, read a few lines and was hooked. I spent the rest of the night reading it.

Plouffe has written the most important political book of the year (for reasons I'll get to in a moment). It's also completely gripping. It reads like a thriller. Even though you know how it ends, you quickly get caught up in every twist and turn of perhaps the most remarkable campaigns in American history.

Along the way, I found myself tearing up when I read about the campaign volunteer who had scrimped and saved ("Grabbed some ramen on the weekends... Didn't take the girl to a movie") so he could donate ten dollars to Obama, and laughed at the funny-in-retrospect tales from the trail (like David Axelrod's BlackBerry crashing at a crucial moment because of glazed donut getting stuck in the trackwheel.)

But it's not the insider look at the past that makes the book so important. It's what it shows us about the present -- and the effect it could have on the future.

Plouffe's book arrives at a crossroads moment for the administration -- exactly one year after the election, and one year before the 2010 midterms. A lot has happened in that year, as the audacity of winning has given way to the timidity of governing. But in recounting how the campaign team -- and the candidate -- not only had the audacity to win but was able to keep that audacity alive, day in and day out over the long nearly-two-year slog of the campaign, Plouffe has also shown the Obama White House the way forward.

The book is a powerful reminder of what the country voted for last year -- and could serve as the trigger for Obama and his team to refocus and remember why the election mattered so much.
