For days, the White House has infuriated its Democratic allies in Congress by offering House Republicans more and more in exchange for a deal to raise the debt ceiling and prevent default. But it was never enough, and, on Friday evening, it became clear that it may never be enough. Speaker John Boehner again walked away from the “grand bargain” he had been negotiating with President Obama, leaving the country teetering on the brink of another economic collapse.

At the White House podium a few minutes later, the president radiated a righteous fury he rarely displays in public, finally placing the blame for this wholly unnecessary crisis squarely where it belongs: on Republicans who will do anything to upend his presidency and dismantle every social program they can find. “Can they say yes to anything?” he asked, noting the paradox of Republicans, who claim that financial responsibility and debt reduction are their biggest priorities, rejecting yet another deal that would have cut that debt by at least $3 trillion.

Mr. Obama, in fact, had already gone much too far in trying to make his deal palatable to House Republicans, offering to cut spending even further than the deficit plan proposed this week by the bipartisan “Gang of Six,” which includes some of the Senate’s most conservative members. The White House was willing to cut $1 trillion in domestic and defense spending and another $650 billion from Medicare, Medicaid and even Social Security.

Much of that savings would have come from raising the eligibility age for Medicare benefits and reducing the cost-of-living increases that elderly people depend on when receiving their health and pension benefits. It could have caused significant damage to some of the nation’s most vulnerable people.
