From a Jim Himes email:

It is clear that the next several years will be the economic equivalent of threading a needle. While we address the massive unfunded liabilities associated with Social Security and Medicare (now well in excess of $50 trillion), we will need to identify the moment at which our nascent recovery is self-sustaining and put on the brakes. If we are to avoid inflation, interest rates will need to go up and government spending will need to go down. Both of those things will be enormously unpopular, but the Federal Reserve and the Congress will need to remember that inflation is far more damaging.

Where does that $50 trillion-plus figure come from? Why from Pete Peterson, of course.

Sara Robinson at CAF:

"The $56 trillion number is what you get if you project the entire U.S. debt a full 75 years into the future, which is how far out you have to go before you can get into numbers that big….Peterson and his posse are laying bets that Americans are too mathematically and logically challenged to notice the flaws in his reasoning—even though the holes are big enough to drive an entire generation of retired Boomers through."

As Robert Kuttner said in the Washington Post, "Most of the number Peterson cites is a combination of the 75-year worst-case projections for Social Security, Medicare and Medicaid."

There’s a huge run that Republicans and ConservaDems are going to make at cutting Social Security benefits. The Republicans because they’ve had a woody to undo the New Deal since it started, and ConservaDems from the Blue Dogs and New Dems (of which Himes is a member) as a way to take the heat off themselves for voting for a bunch of blank check bailouts so they can look "fiscally responsible" in 2010.

It appears Jim Himes is a part of that effort, because that’s where that language comes from.
