On this page last week I argued that Barack Obama’s first budget showed him to be more of a left-leaning liberal than I and many others – sceptics and admirers alike – had previously supposed. People I respect have accused me of going off the deep end about this, or of neglecting Mr Obama’s tactical finesse, or both.

Mr Obama is calling for little that he did not promise in the campaign, I am reminded, so he cannot be accused of springing a surprise. I welcome many of the budget’s main elements, notably healthcare reform and the cap-and-trade system for carbon emissions, and the president made it clear all along that he wished to reverse the Bush tax cuts for the high paid. So the revelation that Mr Obama is a progressive liberal must arise from the proposal to curb high earners’ income-tax deductions. That was a surprise, but a small matter: hence the charge that I am getting carried away.
