June 25, 1966:
At their state convention in Boston, Massachusetts Republicans endorse state Attorney General Edward Brooke as their candidate for the Senate seat being vacated by GOP incumbent Leverett Saltonstall. In winning the endorsement, Brooke defeats conservative activist Alan MacKay, who says that Brooke is a liberal who betrayed his party when he refused to back Republican presidential candidate Barry Goldwater in 1964.
Goldwater, meanwhile, announced his support for Brooke in May.
Democrats are likely to nominate former Gov. Endicott Peabody for the Senate in the September primary. He faces a challenge from Boston Mayor John Collins.
Brooke will easily defeat Peabody for the seat in November, becoming the first black elected to the Senate since Reconstruction.
