From First Read today:

Speaking of health care, how has Obama gone from touting $300 billion in Medicare waste/fraud/abuse savings in June as part of his plan to pay for health care to now claiming the White House has found $500-$600 billion in these savings. The fact is the president still hasn’t release a detailed plan in general, let alone gotten into the “how to pay for” weeds when it comes to exactly how they found yet another $200 billion in cuts. This actually gets at the nut of the president’s potential credibility problem: If there is so much money in waste/fraud/abuse in the Medicare system, then why do we continue to let it happen? Why are we waiting so long to deal with it? The average cynical voter is thinking, “Well, the president may be well meaning, but the bureaucracy that is the American government let this waste/fraud/abuse happen once, who is to say they won’t let it happen again?”
