Jen referred this morning to David Brooks’s column, in which he advises the President to change his ways after the midterm election, especially if it turns out to be as disastrous for Democrats as nearly everyone expects. And this means changing his politics, just as Bill Clinton did after the 1994 midterm:

Obama needs to redefine his identity. Bill Clinton gave himself a New Democrat label. Obama has never categorized himself so clearly. This ambiguity was useful in 2008 when people could project whatever they wanted onto him. But it has been harmful since. Obama came to be defined by his emergency responses to the fiscal crisis — by the things he had to do, not by the things he wanted to do. Then he got defined as an orthodox, big government liberal who lacks deep roots in American culture.

Unlike Clinton, who doesn’t have an ideological bone in his body, I’m not sure Obama has the capacity to do that. I’ve just finished reading Louis Auchincloss’s mini-biography of Woodrow Wilson (part of the “Penguin Lives” series), and I was struck by the similarities between the country’s first liberal president and the man who might be its last (I know, I know, ever the optimist).

Wilson was, at heart, an academic, the author of several books, (including Congressional Government, still in print after 125 years). He thought and acted like a professor even after he entered politics. Wilson always took it for granted, for instance, that he was the smartest guy in the room and acted accordingly. Does that sound familiar? Wilson was a remarkably powerful orator. (It was he who revived the custom of delivering the State of the Union message in person, a custom that had been dropped by Thomas Jefferson, a poor and most reluctant public speaker.)

Both men had very short public careers before the White House. Wilson’s only pre-presidential office was two years as Governor of New Jersey. And Wilson thought he had a pipeline to God, which allowed him to divine what was best for the world and gave him a moral obligation to give it to the world whether the world wanted it or not. This last tendency, evident even when he was president of Princeton University, became more pronounced with age as a series of debilitating strokes (the first at age 40) increasingly rigidified his personality.

Both Wilson and Obama were the subjects of remarkable public adulation, and both won the Nobel Peace Prize for their aspirations rather than their accomplishments. In Wilson’s case, at least, it only increased his sense of being God’s instrument on earth. Although the Republicans had won majorities just before Armistice Day in November 1918, in both houses of Congress — and the Senate’s consent by a two-thirds majority would be necessary to ratify any treaty — Wilson shut them out of any say in the treaty he went to Paris to negotiate with the other victorious powers. Obama, of course, shut the Republicans out of any say in both the stimulus bill and ObamaCare.

The result was disastrous for Wilson’s dream of world peace. So obsessed was he with creating a League of Nations that he was willing to surrender on almost everything else enunciated in his Fourteen Points to get it. Clemenceau and Lloyd George, shrewd and ruthless negotiators, played him like a fiddle. The result was the Treaty of Versailles, perhaps the most catastrophic work of diplomacy in world history, which produced a smoldering resentment in Germany at its harshness, a resentment exploited by Adolf Hitler.

When Wilson returned home, he flatly refused to compromise with the Republicans in the Senate and embarked on a speaking tour to build public pressure to force the treaty and the League through. The result was another stroke that left him incapacitated. The treaty was defeated 55-39, and when the Republicans tried to add a “reservation” that was essentially trivial but would have resulted in ratification, Wilson would have none of it. If he could not have the treaty, word for word, that he had negotiated, then he preferred nothing. He asked Democratic senators to vote against the amended treaty, and they did so. As a result, the United States did not join the League, which was hopelessly ineffective without the world’s greatest power, and what Wilson had hoped would be eternal peace became a 20-year truce.

President Obama, so far as I know, is in the best of health, but will he be any more able to deal with a changed political reality and work with Republicans? I hope so, but even this incorrigible optimist is not too confident of that.
