Then there is Mr. Obama as political tactician. He makes predictions that prove false. He makes promises he cannot honor. He raises expectations he cannot meet. He reneges on commitments made in private. He surrenders positions staked in public. He is absent from issues in which he has a duty to be involved. He is overbearing when he ought to be absent. At the height of the financial panic of 1907, Teddy Roosevelt, who had done much to bring the panic about by inveighing against big business, at least had the good sense to stick to his bear hunt and let J.P. Morgan sort things out. Not so this president, who puts a new twist on an old put-down: Every time he opens his mouth, he subtracts from the sum total of financial capital.

Then there’s his habit of never trimming his sails, much less tacking to the prevailing wind. When Bill Clinton got hammered on health care, he reverted to centrist course and passed welfare reform. When it looked like the Iraq war was going to be lost, George Bush fired Don Rumsfeld and ordered the surge.

Mr. Obama, by contrast, appears to consider himself immune from error. Perhaps this explains why he has now doubled down on Heckuva Job Geithner. It also explains his insulting and politically inept habit of suggesting—whether the issue is health care, or Arab-Israeli peace, or change we can believe in at some point in God’s good time—that the fault always lies in the failure of his audiences to listen attentively. It doesn’t. In politics, a failure of communication is always the fault of the communicator.
