William “Mo” Cowan of Massachusetts is the Senate’s newest member.
Governor Deval Patrick has chosen his former Chief of Staff to fill John Kerry’s Senate seat until a special election is held in June.
One person disappointed by Gov. Deval Patrick’s decision to name Mo Cowan as interim U.S. Senator is former Congressman Barney Frank.
Barney Frank for interim senator? In politics, you never say never. But I doubt it.
