Corey Johnson, one of several likely candidates vying for the seat that will likely be vacated by NYC Council Speaker Chris Quinn in 2013, announced today that he has landed the support of the three openly gay men serving in Congress: Democratic Reps. Barney Frank (Massachusetts), Jared Polis (Colorado) and David Cicilline (Rhode Island).

This comes on the heels of endorsements for Johnson announced yesterday from 577 grassroots leaders, activists and advocates, and the news that the Community Board 4 chairman has already completed the fundraising necessary to reach the legal spending limits for the race – even though the election is still well over a year away.

The battle for the Chelsea seat currently held by Quinn – the city’s first lesbian speaker, who is currently the Democratic frontrunner in the 2013 NYC mayor’s race – is shaping up to be one of the more closely watched NYC Council races.

Johnson’s potential, but yet undeclared, rivals include activist/attorney/radio host Yetta Kurland, who unsuccessfully challenged Quinn in 2009; and Andrew Berman, who is executive director of the Greenwich Village Society for Historical Preservation. A fourth Democrat, Community Board 2 Chairman Brad Hoylman, was expected to run, but has since declared his candidacy for the seat of Quinn’s former boss, retiring Sen. Tom Duane.

Johnson’s campaign released the following statements from the congressmen.

“I first met Corey 13 years ago when he showed courage and inspired a generation of young people by coming out while still in high school and captain of his football team,” said Frank. “Over the years, he has continued to mature as a leader in the fight for justice and equality. I know he will be an outstanding public servant.”

This isn’t the first time Frank, who is retiring at the end of the year, has picked sides in a New York race. In January, he and Rep. Carolyn Maloney co-hosted a fund-raiser for Wappingers Falls Mayor Matt Alexander, who was hoping to take on GOP Rep. Nan Hayworth in November. Alexander a 5-way Democrat primary on June 26 to another openly gay candidate, former Spitzer/Paterson aide Sean Patrick Maloney.

Here’s what Polis had to say:

“Corey is a dear friend. I know him to be a passionate advocate for what he believes in – good jobs for working people, good schools for every child and good government for every American. I can’t imagine a better match than Corey Johnson representing his neighborhood in New York’s City Council.”

…and Cicilline:

“”Before being elected to Congress, I served as mayor of Providence, and I know what it takes to make a good Council member. Corey Johnson has what it takes to advocate for his community and work constructively with City Hall to get results. I am proud to support his campaign.”
