After John Edwards bowed out (and in retrospect, wasn't that a bullet dodged), I was leaning towards Obama over Hillary Clinton. It was his organization that sealed the deal for me. Like the post says, it's "an organization like nothing I've seen before." The Obama campaign has trained thousands upon thousands of people on how to run a political campaign. It has networked self-contained groups of skilled volunteers. It has created the sense of community and urgency that is required to move a campaign forward.
Those of us working to elect Obama share a lot of the same values, and on Nov. 5, a potent political machine is going to wake up, probably hungover, with nothing to do. People have been given the tools - I'm excited to see what we can build with them.
