Is it me or is this presidency beginning to feel like one of those preposterously beset undertakings destined to live on in popular culture as a legendary illustration of Murphy’s Law? Here’s the AP with the latest mishap:

President Barack Obama’s health care law would let several million middle-class people get nearly free insurance meant for the poor, a twist government number crunchers say they discovered only after the complex bill was signed…. Medicare chief actuary Richard Foster says the situation keeps him up at night.. “I don’t generally comment on the pros or cons of policy, but that just doesn’t make sense,” Foster said during a question-and-answer session at a recent professional society meeting. It’s almost like allowing middle-class people to qualify for food stamps, he suggested.

Spiderman on Broadway can always cut its losses, close up shop, and leave the world no worse off. The same cannot be said of a continuously bedeviled presidential administration.
