ATLANTA — Georgia’s term-limited Gov. Nathan Deal took a stand against his own party and averted threatened boycotts by major corporations on Monday by announcing his veto of a “religious freedom” bill. “I do not think that we have to discriminate against anyone to protect the faith-based community in Georgia,” the Republican governor declared. Religious conservatives had campaigned hard for Deal’s signature, but the industries he has recruited to Georgia also applied pressure. The NFL warned that Atlanta’s bid for the 2019 or 2020 Super Bowl could be in jeopardy.
