Clive Crook, whose column from and about America in the Financial Times usually has something interesting to say, yesterday tendered an apology to his Republican readers.

As you recall, in the debate over the fiscal stimulus, Republicans accused the president of presenting a measure they could not support, disguising this with an empty show of co-operation. Bipartisanship, they said, is more than inviting your opponents round for coffee and a chat. I did not buy it: I accused them, in effect, of brainless rejectionism and a refusal to compromise, and congratulated the president for trying to come to terms with the other side.

This budget says the Republicans had Mr Obama right all along. The draft contains no trace of compromise. It makes no gesture, however small, however costless to its larger agenda, of a bipartisan approach to the great questions it addresses. It is a liberal’s dream of a new New Deal.

Take this budget at face value, and when Mr Obama talks about “a new era of responsibility” he does not mean: “We are all in this together.” He means: “The rich are responsible for this mess and it is payback time.” Leftist Democrats are thrilled, and rightly so. The budget has three themes: healthcare reform, public investment and unflinching redistribution. This is indeed a new social contract: we get, they pay. Liberals never had it so good.

For the moment, though, this budget reveals Mr Obama with new clarity. He is no Tony Blair, ideologically rootless, as I had previously suspected. He is a conviction politician: a bold progressive liberal.
