The national debate over gay marriage is heating up in North Carolina where voters will cast their ballots Tuesday on a controversial constitutional amendment that would define marriage as between a man and a woman.
While the Tar Heel State already prohibits same-sex marriage, the proposal would go a step farther and not recognize any type of legal union between couples that aren't married, including civil unions and domestic partnerships.
Adding the ban to the state's constitution would also make it much harder to overturn in the future.
Critics say the law would jepoparize health insurance benefits for unmarried gay and straight couples, while proponents say it would preserve the traditional definition of marriage between a man and a woman.
Former President Bill Clinton urged voters in a robo-call this week to vote against the amendment, and
President Obama's North Carolina spokesman has previously issued a statement saying Obama was against the measure.
"What it will change is North Carolina's ability to keep good businesses, attract new jobs, and attract and keep talented entrepreneurs," Clinton says in the call. "If it passes, your ability to keep those businesses, get those jobs, and get those talented entrepreneurs will be weakened."
Meanwhile, evangelist
Billy Graham and former GOP presidential candidate
Newt Gingrich have thrown their support behind the measure.
The proposal comes as President Obama is scrutinized for his stance on gay marriage after
Vice President Joe Biden said Sunday that he was "absolutely comfortable" with it.
The President, who supports most gay rights, has stopped short of fully backing same-sex marriage, insisting his personal views on the issue were "evolving."
More than 500,000 voters had already cast absentee ballots.
