NBC News New York reports that two Republican Senate seats would likely switch to Democrats. That would leave the chamber tied 31-31. But those seats aren’t officially decided yet. Thousands of absentee ballots need to be counted, and that could change the razor-thin winning margins.

Veteran Republican Senator Stephen Saland from Poughkeepsie voted to support gay marriage. He was losing by about 1,500 votes. But the Poughkeepsie Journal reported that as of 1:30 a.m., Saland hadn’t conceded to Democrat Terry Gipson.

In Rochester, Democrat Ted O'Brien appears to have defeated Republican Sean Hanna. That seat had been held by another Republican, James Alesi, who also voted for same-sex marriage.

Also, a new seat in the capital region created by the Republican majority to help seal its control is still too close to call. It pitted Republican George Amedore against Democrat Cecilia Tkaczyk in the 46th Senate District.

There are still thousands of absentee ballots yet to count in that race.

Meanwhile, both Republicans and Democrats have declared Election Day victories in New York.
