The state-to-state march to legalize gay marriage across the left-leaning Northeast has lost more momentum since a major setback three weeks ago at the ballot box in Maine.

Since then, legislatures in New York and New Jersey have failed to schedule long-expected votes on bills to recognize the unions in those states.

"If they are unable to pass gay marriage in New York and New Jersey, combined with the loss in Maine, it will confirm that gay marriage is not the inevitable wave of the future," said Maggie Gallagher, president of the National Organization for Marriage, which mobilizes social conservatives to fight against same-sex unions.

Gay rights activists insist that's not the case and say hope is still alive.

"In any civil rights struggle there are going to be periods of creeping and periods of leaping," said Evan Wolfson, executive director of Freedom to Marry.

This decade has had some of both across the country. The most significant was the leap the issue made from abstraction to reality in 2003 when the Massachusetts Supreme Court ruled that gay couples had the right to get married.
