New York Gov. Andrew Cuomo says he’s confident the bill will pass.

A vote on marriage equality in New York, the nation’s third-largest state behind California and Texas, could come in the next few days. According to the New York Times, three Democrats and a Republican who voted against marriage equality in the last session now say they will vote for it. All but one Democrat in the state Senate now supports marriage equality.

According to the Albany Times Union, that brings the number of votes committed to equality in the Senate to 29, just three short of passage. Rochester’s Democrat and Chronicle has the count up to 30 in favor, with just two more votes needed.

A rally in support of marriage equality is planned for 11:30 a.m. Tuesday at New York City Hall.

If the bill passes, the number of people living in states where same-sex marriage is legal will more than double. New York’s population of 19.3 million is larger than the total population of the five states and D.C. that currently allow same-sex marriage.
