David Brooks was disappointed the other day that President Obama is acting like a politician.

Yes, I’m a sap. I believed Obama when he said he wanted to move beyond the stale ideological debates that have paralyzed this country. I always believe that Obama is on the verge of breaking out of the conventional categories and embracing one of the many bipartisan reform packages that are floating around.

But remember, I’m a sap. The White House has clearly decided that in a town of intransigent Republicans and mean ideologues, it has to be mean and intransigent too. The president was stung by the liberal charge that he was outmaneuvered during the debt-ceiling fight. So the White House has moved away from the Reasonable Man approach or the centrist Clinton approach.

Shorter version: You mean he’s actually going to fight back? Well, that’s so… disappointing.
