Who gets the credit for Obama’s win?

We’ve talked (and you’ve written) a lot about the GOP searching for its identity in the ashes of the election. The corresponding soul-searching in the Democratic Party is over who’s responsible for the big victory (and therefore who should get a bigger piece of the power pie). For example, Latinos point to big wins in Florida, Colorado, and Nevada (http://www.mlive.com/us-politics/index.ssf/2008/11/latinos_push_for_cabinet_posts.html).

Vermont’s Howard Dean, chairman of the Democratic National Committee, is claiming credit due to his “50 State Strategy”. Dean pushed Democrats deeper into rural America the last four years than they had been in a long time. Still, today the New York Times considers whether the Dean strategy was a cause or just a parallel phenomenon to the Obama machine. http://www.nytimes.com/2008/11/12/us/politics/12web-nagourney.html?hp

What do you think? Who led and who followed? And what does that say about how Obama should govern?
