The speech was an unusual and unleavened assault on the Republican Party. As such it was gutsy, no doubt sincere and arguably a little mad. The other party in a two-party center-right nation is anathema? There was no good-natured pledging to work together or find common ground, no argument that progress is possible. The GOP “will brook no compromise,” it is “peddling” destructive economic nostrums, it has “a radical vision” and wants to “let businesses pollute more,” “gut education,” and lay off firemen and cops. He said he is not speaking only of groups or factions within the GOP: “This is now the party’s governing platform.” Its leaders lack “humility.” Their claims to concern about the deficit are “laughable.”

The speech was not aimed at healing, ameliorating differences, or joining together. The president was not even trying to appear to be pursing unity. He must think that is not possible for him now, as a stance.

There was a dissonance at the speech’s core. It was aimed at the center—he seemed to be arguing that to the extent he has not succeeded as president, it is because he was moderate, high-minded and took the long view—but lacked a centrist tone and spirit…

I guess what’s most interesting is that it’s all us-versus-them. Normally at this point, early in an election year, an incumbent president operates within a rounded, nonthreatening blur. He’s sort of in a benign cloud, and then pokes his way out of it with strong, edged statements as the year progresses. Mr. Obama isn’t doing this. He wants it all stark and sharply defined early on. Is this good politics? It is unusual politics. Past presidents in crises have been sunny embracers.
