ROSS DOUTHAT: The Great Immigration Betrayal: “We now have a clearer sense of just how anti-democratically this president may be willing to proceed.”

So there is no public will at work here. There is only the will to power of this White House.

Which is why the thinking liberal’s move, if this action goes forward, will be to invoke structural forces, flaws inherent in our constitutional order, to justify Obama’s unilateralism. This won’t be a completely fallacious argument: Presidential systems like ours have a long record, especially in Latin America, of producing standoffs between executive and legislative branches, which tends to make executive power grabs more likely. In the United States this tendency has been less dangerous — our imperial presidency has grown on us gradually; the worst overreaches have often been rolled back. But we do seem to be in an era whose various forces — our open-ended post-9/11 wars, the ideological uniformity of the parties — are making a kind of creeping caudillismo more likely.

But if that evil must come, woe to the president who chooses it. And make no mistake, the president is free to choose. No immediate crisis forces his hand; no doom awaits the country if he waits. He once campaigned on constitutionalism and executive restraint; he once abjured exactly this power. There is still time for him to respect the limits of his office, the lines of authority established by the Constitution, the outcome of the last election.

Or he can choose the power grab, and the accompanying disgrace.

He’s not worried about disgrace, because he expects the press to cover for him.
