New York state Senator Stephen Saland of Poughkeepsie has won his GOP primary, while Senator Roy McDonald of Saratoga County remains hopeful.

Saland and McDonald were among the four Republicans who last year crossed the aisle to vote with all but one Democrat to legalize gay marriage in New York, making it the most populous state yet to do so.

Senator Mark Grisanti of Buffalo won his primary with a comfortable margin. James Alesi of Rochester, the fourth senator, retired.

According to the Poughkeepsie Journal, Saland was declared the winner with a margin of 107 votes after absentee and affidavit ballots were counted.

McDonald fell further behind on Monday as officials began counting paper ballots, but the incumbent wasn't ready to concede. reported that McDonald's GOP rival, Kathy Marchione, was leading by 113 votes.

“I think it is inevitable that Kathy Marchione will be the Republican nominee for the state Senate seat,” said Mike Cuevas, a spokesman for Marchione.

Jeff Buley, an attorney for the the McDonald campaign, said the senator “plans on running on the Independence line.”

Marriage equality foes had vowed to cut short the political lives of the four Republicans. Knocking them out in the GOP primary, which includes a higher percentage of conservative voters, is easier than during the general election.
