What Made Obama's Speech Great

We are on the cusp of a new politics in America. It should be dated from March 18, 2008, the date of Barack Obama's landmark speech "A More Perfect Union." The usual pundits have looked mainly at the speech's surface theme: race. They weren't wrong. It was indeed the most important statement about race in recent history.

But it was much more. It was a general call to a new politics and an outline for what it needs to be. Just as Lincoln's Gettysburg Address was about much more than the war dead on that battlefield, so Obama's speech -- widely hailed as in the same ballpark as Lincoln's -- went beyond race to the nature of America, its ideals and its future.

To get an appreciation for the greatness of Obama's speech, we have to start with its context: What were the problems Obama faced in writing it, and what were the constraints on him?

He was under severe political attack, both from Republican conservatives and from the Clinton wing of his own party. Here's what he was facing:

• Racial divisions and identity politics had been injected into the campaign by his opponents and the media. The effect was to position him, as an African-American, as being opposed to the interests of whites and Hispanics.
• An attack on his and his wife's patriotism.
• A claim that he was really a Muslim.
• A repeatedly shown film clip of his long-time pastor, Jeremiah Wright, who had married him and his wife and baptized his daughters, making embarrassing remarks taken as anti-American and anti-Semitic.
• One of the hallmarks of his campaign has been good judgment on foreign policy; his opponents claimed that his connection to Wright had shown bad judgment.
• Another hallmark of his campaign has been authenticity, telling the truth. Two of his advisors had made remarks -- one on NAFTA and one on Iraq -- that opponents had twisted to make it seem that he was lying. He had to establish himself as truthful.
• Another hallmark of his campaign has been values. His opponents had claimed that his values were unknown and that the public didn't know who he was.
• His opponents had claimed that he could not stand up to strong opposition.
• He was in the center of an intensely divisive campaign while pressing unity as a major theme.
• His opponents had claimed that his eloquence was all talk and no action.

In addition, Sen. Obama faced certain constraints on what he could say:
