Deval Patrick got a shout-out from an old pal during a radio appearance today: President Obama.“Deval, you’ve done good, man,” the president said, calling in to the governor’s weekly “Ask the Governor” with Jim Braude and Margery Eagan on WGBH. “I just wanted to let my dear friend know how proud I am.”Obama, a Harvard Law grad, introduced himself as “formerly of Somerville.”“I’ve got a few complaints about service in and around the neighborhood,” he quipped to Patrick.
