orth Carolina voters approved a constitutional amendment on Tuesday defining marriage solely as a union between a man and a woman, making it the 30th state to adopt such a ban. With 35 percent of precincts reporting Tuesday, unofficial returns showed the amendment passing with about 58 percent of the vote to 42 percent against. In the final days before the vote, members of President Barack Obama's cabinet expressed support for gay marriage and former President Bill Clinton recorded phone messages urging voters to reject the amendment. Opponents also held marches, ran TV ads and gave speeches, including one by Jay Bakker, son of televangelists Jim Bakker and the late Tammy Faye Bakker.
