Six months ago President Obama faced a hostage situation. Republicans threatened to block an extension of middle-class tax cuts unless Mr. Obama gave in and extended tax cuts for the rich too. And the president essentially folded, giving the G.O.P. everything it wanted.
Now, predictably, the hostage-takers are back: blackmail worked well last December, so why not try it again? This time House Republicans say they will refuse to raise the debt ceiling — a step that could inflict major economic damage — unless Mr. Obama agrees to large spending cuts, even as they rule out any tax increase whatsoever. And the question becomes what, if anything, will get the president to say no.
The debt ceiling itself is a strange feature of U.S. law: since Congress must vote to authorize spending and choose tax rates, why have a second vote on whether to allow the borrowing that these spending and taxation policies imply? In practice, however, legislators have historically been willing to raise the debt ceiling as necessary, so this quirk in our system hasn’t mattered very much — until now.
What has changed? The answer is the radicalization of the Republican Party. Normally, a party controlling neither the White House nor the Senate would acknowledge that it isn’t in a position to impose its agenda on the nation. But the modern G.O.P. doesn’t believe in following normal rules.
