Dead on, again.  It's been starkly obvious that Obama has been running a classic neighborhood organizing campaign, writ large.  His community work in Chi Town seems to have stuck with him.

Notable, is that the feedback loop goes two ways - Obama's message is delivered, and responses and actions from the public are actively sought.  Then the engaged electorate is offered the opportunity to become more deeply involved in the campaign - through donations, becoming block captains, rallies, etc.  And the web grows ever closer while spreading outwards, organically.  Those volunteers and donors are now informed, empowered and motivated.

This organizing style is not inherently reflective of any political viewpoint, though it does favor the populist and progressive outlooks. John McCain could also try to make use of it.  Likely he won't and would have cognitive dissonance issues if he did.  That's why the Republican's electoral successes have been built on turning out church congregations, who are already conditioned to respond to signals from their leadership hierarchy, and who have reflexive, linear organizations.

Obama's popularity reflects a lot more than his charisma.  People are hungry for the tools and education that lets them attack their own problems constructively.  Bush only wants passive shoppers.

This doesn't mean that Obama is at root any less of a center-right Democrat, but it's inspiring to watch this play out.
