If you were not one of the 2 million people watching the inauguration on the Mall in Washington, you could watch the spectacle on any number of television channels. Flipping between ABC, CBS, NBC and PBS would have yielded different commentary but largely the same mood: euphoria, awe at the magnitude of electing the first African-American president, and somber urgency about what confronts our financial system and the world. Yet, even as Obama warned of a difficult road, the crowds were wildly enthusiastic, and millions were moved. Main Street has turned a corner.
