Here’s a thread to discuss the latest reports on the debt ceiling talks, as President Obama reportedly offers to make cuts in Social Security.

As part of his pitch, Obama is proposing significant reductions in Medicare spending and for the first time is offering to tackle the rising cost of Social Security, according to people in both parties with knowledge of the proposal. The move marks a major shift for the White House and could present a direct challenge to Democratic lawmakers who have vowed to protect health and retirement benefits from the assault on government spending.

“Obviously, there will be some Democrats who don’t believe we need to do entitlement reform. But there seems to be some hunger to do something of some significance,” said a Democratic official familiar with the administration’s thinking. “These moments come along at most once a decade. And it would be a real mistake if we let it pass us by.”

Rather than roughly $2 trillion in savings, the White House is now seeking a plan that would slash more than $4 trillion from annual budget deficits over the next decade, stabilize borrowing, and defuse the biggest budgetary time bombs that are set to explode as the cost of health care rises and the nation’s population ages.

That would represent a major legislative achievement, but it would also put Obama and GOP leaders at odds with major factions of their own parties. While Democrats would be asked to cut social-safety-net programs, Republicans would be asked to raise taxes, perhaps by letting tax breaks for the nation’s wealthiest households expire on schedule at the end of next year.

That’s the Washington Post’s take, anyway — but White House spokesman Jay Carney said today that their report was exaggerated and “overwritten:” White House: No Change In Obama’s Position On Social Security.
