ROSS DOUTHAT: Obama’s Impeachment Game.

Over the last month, the Obama political apparatus — a close aide to the president, the Democratic Congressional Campaign Committee and the “independent” voices at MSNBC — has been talking nonstop about an alleged Republican plan to impeach the president. John Boehner’s symbolic lawsuit against the White House has been dubbed “impeachment lite,” Sarah Palin’s pleas for attention have been creatively reinterpreted as G.O.P. marching orders, and an entire apocalyptic fund-raising campaign has been built around the specter of a House impeachment vote.

Anyone paying attention knows that no such impeachment plan is currently afoot. So taken on its own, the impeachment chatter would simply be an unseemly, un-presidential attempt to raise money and get out the 2014 vote.

But it isn’t happening in a vacuum, because even as his team plays the impeachment card with gusto, the president is contemplating — indeed, all but promising — an extraordinary abuse of office: the granting of temporary legal status, by executive fiat, to up to half the country’s population of illegal immigrants. . . .

This simply does not happen in our politics. Presidents are granted broad powers over foreign policy, and they tend to push the envelope substantially in wartime. But domestic power grabs are usually modest in scope, and executive orders usually work around the margins of hotly contested issues. . . .

This is the tone of the media coverage right now: The president may get the occasional rebuke for impeachment-baiting, but what the White House wants to do on immigration is assumed to be reasonable, legitimate, within normal political bounds.

It is not: It would be lawless, reckless, a leap into the antidemocratic dark.

And an American political class that lets this Rubicon be crossed without demurral will deserve to live with the consequences for the republic, in what remains of this presidency and in presidencies yet to come.

Yep. But Obama doesn’t care. And neither do his enablers. But I think it’s worth stressing that any sort of unilateral executive action on amnesty would constitute nothing less than an extraconstitutional coup.
