Run, don't walk, to go watch Max Harper's detailed presentation on the "Hope Factory," the Obama campaign's system for connecting media, membership, fundraising and activism over the course of 2008 race. I've seen and participated in dozens of talks on "how they did it" but never heard anyone put it all together in one place in quite the way Harper does. Harper joined the Obama video team in July 2008, where he piloted the concept for the "Blueprint for Change" videos. Harper's talk is anchored around how the campaign understand the various uses of video, but as you'll see, he offers an overarching analysis of how all the parts fit together that strategists of all stripes will want to study.
