Top 10 Reasons Obama Defeated Clinton for the Democratic Nomination

Now that the outcome of the battle for the Democratic nomination has been settled beyond a reasonable doubt, it's worth looking systematically at the major factors that gave victory to Obama. After all, fifteen months ago, conventional wisdom viewed Obama as an audacious long shot. The very idea of a first-term African American senator with a name like Barack Obama defeating the vaunted Clinton machine seemed preposterous.

Here are my Top Ten reasons why lightning struck in the contest for the 2008 Democratic nomination (apologies to David Letterman ):

#10. Great Team. Obama assembled a great team that could work together. He stayed away from lobbyist insiders like Clinton's Mark Penn or McCain's Charlie Black, and choose political professionals who are committed to progressive values like David Plouffe, David Axelrod, Steve Hildebrand and Paul Tewes. From the first he insisted on one key rule: no drama. There was little of the infighting and division in the Obama operation that ate away at the Clinton campaign. Clinton had many capable staffers and consultants, but Penn's divisive leadership style and failures as a strategist doomed the campaign organization to dysfunction. When the brilliant Geoff Garin was tapped to succeed Penn as Chief Strategist in April, it was simply too late.

#9. All-State Strategy. Mark Penn was convinced that Clinton could sew up the nomination by Super Tuesday focusing only on the big states. In fact, some have reported that he mistakenly believed that California had a "winner take all" primary. Obama's team hunted for delegates in every nook and cranny of America -- especially in the caucus states that Clinton really didn't contest. Obama ran an active, on-the-ground campaign in every contest, from California to Guam. As a consequence, as one anonymous Clinton insider reports, Clinton lost the nomination in February after Obama ran the table in 11 straight states.

#8. No Plan B. The Clinton campaign had no fall-back plan when it failed to capture the nomination on February 5. There was no money, no organization and no plan to contest the states that lie in the land beyond Super Tuesday.

#7. Excellence in Execution: Great Field. Obama ran the best field operation in American political history -- particularly in the all important Iowa Caucuses. His campaign left no stone unturned, or a vote on the table, in any state. It opened offices everywhere, hired and trained great staff, and managed through simple, streamlined structures. It would have been easy for Obama to squander the massive influx of volunteers who were mobilized through his inspirational message. But the campaign developed structures to integrate and effectively use volunteers, both on the ground and through the Internet. In particular, it developed highly sophisticated new Internet tools to allow volunteers around the country to participate meaningfully in voter ID and get out the vote operations.

#6. Explosive Obama Fundraising. Obama's ability to compete everywhere, to build great field structures and to out-communicate Clinton in the paid media rested squarely on the massive fundraising operation. Obama's traditional fundraising program ended up matching the vaunted Clinton fundraising machine. But the newly developed Internet operation provided a massive advantage. So far Obama has recruited over one-and-a-half-million donors. In other words, by the time the primary season ends, almost one of every ten Obama primary voters (so far there have been 16.3 million) will have made a financial contribution to his campaign. That is beyond unprecedented.

#5. Obama Out-Communicated Clinton Using One Consistent Message. Obama's message has been consistent from Day One. Clinton lurched from "experienced insider" to "populist outsider" from Margaret Thatcher-like "Iron Lady" to a "victim being bullied." And of course, Obama's huge small-donor-driven fundraising advantage gave him the ability to out-communicate her in the paid media -- often by a factor of two-to-one.
