New Mexico Republicans this week introduced a flurry of bills to ban the state from recognizing the unions of gay and lesbian couples, the New Mexico Independent reported.

Representative David Chavez is backing two bills.

One measure seeks to define marriage as a heterosexual union in the New Mexico Constitution. The second bill would ban the state from recognizing the out-of-state marriages of gay couples.

A third House bill introduced by Representative Nora Espinoza would also ban gay marriage with a constitutional amendment.

In the Senate, Senator William Sharer is also backing a bill that would define marriage as between one man and one woman.

Gay unions have become a contentious issue in previous sessions as activists lobbied for domestic partnerships, while opponents pitched gay marriage ban simultaneously.

But the dynamics in this session might have tipped in favor of ban supporters.

Unlike previous Democratic governors, Republican Governor Susana Martinez opposes any recognition of gay unions.

Three weeks ago, Attorney General Gary King concluded that the out-of-state marriages of gay couples are likely valid in New Mexico, uniting gay marriage foes.

“I believe that the citizens of New Mexico, not only have a right, but have an obligation to define their own culture,” Sharer told the AP. “Culture should not be defined by a judge or an attorney general. This is something that the citizens of New Mexico ought to have a right to vote on.”
