New Hampshire ? The state House on Thursday voted narrowly to make New Hampshire the third state to allow gay couples to marry.

The bill, which passed the House 186-179, next goes to the Senate, where its future is uncertain. Democratic Gov. John Lynch opposes gay marriage but has not said specifically that he would veto it — a position that spokesman Colin Manning reiterated after the vote.

Two years ago, the Legislature approved, and Lynch signed, civil unions for gays, which provide all the rights of marriage, except in name.

Currently, only Connecticut and Massachusetts allow gay couples to marry. The Vermont Senate sent a gay marriage bill to the House this week, but Gov. Jim Douglas says he will veto it if it reaches his desk.
