The New Hampshire House is set to vote next week on a bill which would repeal the state's 2-year-old gay marriage law.

Rep. David Bates' bill would end gay nuptials in the state and give gay couples civil unions, instead. Bates, a Republican, said on Tuesday that he would introduce an amendment to the bill calling for a non-binding ballot question on the issue. Repeal would only take effect on March 31, 2013 if voters agreed in November, he said.

Bates, who has disputed the accuracy of polls showing that a majority of voters support the current law, said his referendum would let the voters weigh in on the issue.

“There will be no more guessing, no more arguing or debating over dueling polls, just the actual voice of the people telling us what their will is on this issue,” Bates told reporters.

Republican Rep. Seth Cohn is also expected to introduce an amendment to the bill. Cohn's amendment would bar a left-handed person from marrying another left-handed person.

While Republicans control the House with a large majority, they are not united in their opposition to repealing the gay marriage law. In fact, a measure this week which sought to allow business owners to withhold wedding-related goods and services to gay couples if they believe it would violate their conscience or religious faith was overwhelmingly rejected with a 246-85 vote. With 105 Democrats in the House, at least 141 Republicans voted to kill the bill, which suggests that the upcoming vote could be much closer than previously thought.
