Howard Fineman:

WASHINGTON – The Obama Administration began at midnight Sunday. Okay, I exaggerate.But I am trying to make a point.Which is this: Even if Sen. Barack Obama loses the presidential election — and of course he may — the playing field of our politics now has shifted seismically in his philosophical direction.The era of cowboy capitalism has died, largely of self-inflicted wounds. Who knows what’s coming now? I do: A new era of tight business regulation and government intervention in the markets.For now, and perhaps for many years, there will be no going back.
