Former Massachusetts Sen. Scott Brown tells a Boston Radio Station he won't be a candidate for Massachusetts governor next year.

The former Republican senator and state lawmaker had been mentioned as a possible GOP candidate. Democratic Gov. Deval Patrick is not seeking a third term. Brown had told supporters at the Iowa State Fair on Sunday that he is "exploring a possible run'' for president in 2016.

Another Republican believed to be weighing a gubernatorial bid is Charles Baker, the former CEO of Harvard Pilgrim Health Care and the 2010 GOP nominee for governor. Several Democrats are running.
