Lots of people think John Boehner has lost control of the House Republican caucus. Apparently John Boehner does, too.

On Wednesday, the speaker and his lieutenants had to stage yet another embarrassing retreat—this time, by postponing a vote on a “continuing resolution” that would fund government operations past September 30, when the current CR expires. Figuring out a way to pass such a bill has been one of Boehner’s biggest challenges for the last few weeks. And primarily that’s because the Republican Party's right wing insists on linking a CR to Obamacare. Both in the House and in the Senate, Tea Party Republicans and their allies want the president’s health care law off the books or, at the very least, delayed and defunded. If they don’t get their way, they say, they won’t vote for any CR—even if that means the federal government shuts down.

Most members of the Republican establishment think this strategy is nuts. Senate Democrats would never agree to undermine Obamacare, they note. And even if a few Senate Democrats went along, enough to get such a measure through the chamber, President Obama would never sign such a bill. It's his signature accomplishment and, for liberals, the biggest achievement since the Great Society. The shutdown that ensued would be bad for the country and, if the polls are right, most voters would blame the Republicans.

As of a few days ago, House leadership thought they’d come up with a solution: They’d pass a CR and include a provision to defund or delay Obamacare, but in a way that allowed the Senate to remove the Obamacare provision. The president would get a “clean” CR to sign, while congressional Republicans could tell their constituents and supporters they’d voted to get rid of Obamacare. Just to sweeten the deal, House leaders made sure the new CR would lock in lower levels of discretionary spending while bumping up defense spending—a position Obama and the Democrats oppose, but probably not enough to block such a proposal. House leaders also promised to stage a real, no-surrender fight on Obamacare later in October, when the federal government would need new authority to keep borrowing money.

Alas, the ploy failed—miserably. Michael Needham, chief executive officer of Heritage Action, called the leadership plan a "legislative gimmick" and warned, darkly, "it is our expectation that no conservative in Congress will try to deceive their constituents by going along with this cynical ploy." Over in the Senate, Texas Republican and conservative agitator Ted Cruz was equally hostile to the idea: “If House Republicans go along with this strategy, they will be complicit in the disaster that is Obamacare.”
