On its website, the Boston Globe reports Massachusetts Treasurer Timothy Cahill has annouced he will run for governor next year as an independent. Cahill left the Democratic Party earlier this year. A late July poll showed Cahill tying Democratic incumbent Gov. Deval Patrick against two possible Republicans, Charlie Baker and Christy Mihos, both of whom trailed. Mihos, who himself ran for governor as an independent in 2006, is considering switching from the gubernatorial race to the race for the Senate seat of the late Edward Kennedy.
