Well, that wasn’t necessarily so, as the president eventually acknowledged. There would undoubtedly be changes in some people’s coverage as a result of “reform,” and some of those changes would be substantial. At a forum sponsored by ABC News last summer, Mr. Obama backed off of his frequent promise that no changes would occur, saying only that “if you are happy with your plan, and if you are happy with your doctor, we don’t want you to have to change.”

These less-than-candid instances are emblematic of much bigger problems. Mr. Obama promised during the campaign that he would be a different kind of president, one who would preside over a more open, more high-minded administration that would be far more in touch with the economic needs of ordinary working Americans. But no sooner was he elected than he put together an economic team that would protect, above all, the interests of Wall Street, the pharmaceutical industry, the health insurance companies, and so on.

How can you look out for the interests of working people with Tim Geithner whispering in one ear and Larry Summers in the other?

Now with his poll numbers down and the Democrats’ filibuster-proof margin in the Senate about to vanish, Mr. Obama is trying again to position himself as a champion of the middle class. Suddenly, with the public appalled at the scandalous way the health care legislation was put together, and with Democrats facing a possible debacle in the fall, Mr. Obama is back in campaign mode. Every other utterance is about “fighting” for the middle class, “fighting” for jobs, “fighting” against the big bad banks.

The president who has been aloof and remote and a pushover for the health insurance and pharmaceutical industries, who has been locked in the troubling embrace of the Geithners and Summers and Ben Bernankes of the world, all of a sudden is a man of the people. But even as he is promising to fight for jobs, a very expensive proposition, he’s proposing a spending freeze that can only hurt job-creating efforts.

Mr. Obama will deliver his State of the Union address Wednesday night. The word is that he will offer some small bore assistance to the middle class. But more important than the content of this speech will be whether the president really means what he says. Americans want to know what he stands for, where his line in the sand is, what he’ll really fight for, and where he wants to lead this nation.

They want to know who their president really is.
