Gingrich video urges NC voters to pass anti-gay marriage amendment

While same sex marriage is already outlawed in the state, the new referendum, known as Amendment 1, would ban marriage equality under the state constitution as well. The measure would not only bar gay and lesbian unions, but also heterosexual domestic partnerships and civil unions.

Polls show a majority of North Carolina voters oppose Amendment 1, and prominent Democrats are speaking out against the legislation's strict guidelines. Last month, President Obama called the bill a "divisive and discriminatory effort" to take away rights from the gay, lesbian, bisexual or transgender (LGBT) community.

"While the president does not weigh in on every single ballot measure in every state, the record is clear that the president has long opposed divisive and discriminatory efforts to deny rights and benefits to same-sex couples," said Cameron French, Obama's North Carolina campaign spokesman. "That’s what the North Carolina ballot initiative would do — it would single out and discriminate against committed gay and lesbian couples — and that’s why the president does not support it."

Gingrich has sought to position himself as the conservative alternative to presumptive GOP nominee Mitt Romney and his new video is another attempt to boost his support among evangelicals.

"Marriage between a man and a woman is at the heart of our civilization. It's a belief that is now under attack, yet it's at the very core of defining who we are. That's why I urge you to vote for the initiative right here in North Carolina," Gingrich says in the web ad. 

"This is part of the same great process this year that's involved with President Obama, and that's involved with the whole danger of what's happening to our basic beliefs."
