The nature of Speaker John Boehner’s final battle with the White House on the budget crisis is now clear: It doesn’t matter what House Republicans win in exchange for raising the debt ceiling and re-opening government, as long as they win something.

Gone is the big talk about “defunding Obamacare.” Gone are the demands for delaying the health law, or delaying the individual mandate, or delaying the medical device tax. The final stand, according to the latest reports, is simply this: remove the health insurance subsidies for members of Congress, some executive branch officials, and some of their staffs. (Those staff members are furious about the potential cut to their incomes, and many have threatened to quit.)



If that seems a paltry prize to win for causing this destructive, embarrassing crisis, that’s because it is. But this fight really has nothing to do with the subsidies. It’s all about not walking away empty handed, about Mr. Boehner persuading his Republican members that they forced President Obama to give something up in exchange for not wreaking havoc on the economy.

And that’s precisely why the president can’t agree to it, even though the impact (for all but Congressional staffers) would be minimal.

For the sake of the rest of his presidency, and the presidents to come, he has to make it clear that no chamber of Congress can back the White House into a corner by threatening the full faith and credit of the United States. Even a small concession, like ending the Congressional subsidies, would betray that principle.

Of course that position is irreconcilable with the hard-right faction of the House that sees the debt ceiling as the only leverage that can turn them into a real political force. But the unprecedented use of that leverage has to be stopped here, even at a terrible cost, because the long-term cost would be so much worse.

Once Senate Republicans and Democrats began cobbling together their own plan, Mr. Boehner could have ended the crisis by standing back and letting momentum for the Senate plan build. Instead, he chose to sabotage it, because he and the Tea Party faction clearly want to use the power of hostage-taking again.

One of the provisions in the House’s latest plan is a demand that the Treasury not use any special measures to prevent default the next time the debt hits the ceiling — a provision, in other words, that would make default an even more likely possibility the next time than it will be on Thursday, when the Treasury runs out of borrowing authority. (The actual default will probably occur later this month.)

Mr. Boehner may hope that the diminished nature of his final demand about Congressional subsidies will embarrass Democrats into approving it, but his tactics are as dangerous as ever.
