Web Extra: As Fed's Debt Rating Gets Downgraded, Mass. Rating Could Go Up

Stock markets dropped Monday in the first day of trading since the rating agency Standard & Poor's downgraded the U.S. credit rating from the stellar AAA rating, to the still-pretty-good-but-not-as-stellar AA+.

Right now the state has a AA rating — lower than even the country's new AA+ rating. But as David Hitchcock explains, the state's rating is still pretty good, and has the potential to get even better.
