UPDATE: After an introduction by Congressman David Loebsack (D-IA), Obama talks about how he can help "change occur," video (03:32).
Mark Schmitt (The American Prospect):
The phrase "theory of change" is a bit of jargon that I first encountered in the philanthropic and non-profit world, where it refers to a fairly new way of evaluating the effectiveness of projects by drawing out the underlying assumptions about how they lead to social change. If we understand Obama's approach as a means, and not the limit of what he understands about American politics, it has great promise as a theory of change, probably greater promise than either "work for it" or "demand it," although we'll need a large dose of hard work and an engaged social movement as well.Howie P.S.: Ben Smith summarizes Obama's "theory of change" today by quoting him on the campaign trail:
"I reach out to Republicans and independents even though I stick to my guns when it comes to policy and positions," he said. "If we use a different language, we can get those supporters. If we go in saying Republicans are bad, evil people, then we can’t."
