Barney Frank, one day out of Congress, said on Friday that he has asked Massachusetts Gov. Deval Patrick to send him back as an interim senator when Sen. John Kerry becomes secretary of state. “A month ago, or a few weeks ago, I said I wasn’t interested,” Frank said on MSNBC’s “Morning Joe.” “It was kind of like you’re about to graduate, and they said: ‘You gotta go to summer school.’ But [the fiscal cliff deal] now means that February, March and April are going to be among the most important months in American financial history.” He added, “I’ve told the governor I would now like, frankly, to do that [serve as interim senator].” Frank said he wouldn’t run for Kerry’s seat in a special election, which would most likely take place this summer. Other names mentioned as a possible caretaker for Kerry’s seat include former Massachusetts Gov. Michael Dukakis and former Massachusetts Supreme Court Justice Margaret Marshall — who crafted the historic ruling legalizing marriage equality in the Bay State.
