New York Attorney General Andrew Cuomo seems to be trying to clean up old business before departing for a run at the Governor’s office, but his latest investigationinto the ratings agencies seems not only strangely timed, but strange in approach.

I’ll be the first to tell you (and did in my book many times) that the ratings agencies— Standard & Poor's, Fitch Ratings and Moody's Investment Service—were a key part of the chain of deception that led our financial markets to near ruin.
