Matt Doheny formally endorsed on Friday his one-time Republican opponent in the 21st congressional district, Elise Stefanik.

In doing so, Doheny declared that he’s “not Doug Hoffman” — the Conservative Party candidate in 2011 and 2012 who remained in the race, and may have helped tilt the balance in favor of Democratic Rep. Bill Owens.

Doheny retains the Independence Party line this fall, but his endorsement of Stefanik today is an indication he won’t campaign actively for the seat that’s been vacating by the retiring Owens at the end of the year.

“I want to thank Matt Doheny for his support,” Stefnik said. “Matt waged a hard fought primary and we respect and appreciate his decision to give Republicans their best opportunity to win back our seat for the North Country. Now is the time to unite not just Republicans, but members of the Independence Party and Democrats interested in bringing new ideas and a new generation of leadership to Washington on behalf of New York’s 21st Congressional District.”

Republicans have long eyed taking the North Country congressional district back from Democratic hands after President Obama tapped GOP Rep. John McHugh to became secretary of the Army.

The decision by Doheny to support Stefanik was praised by National Republican Campaign Chairman Greg Walden.

“Throughout his career, Matt Doheny has always done what is best for the North Country,” Walden said. “Today he continued to do so by helping to ensure that Republican Elise Stefanik will be able to fight for North Country families in Congress. I applaud Matt for making this tough decision and wish him, his wife Mary and their son Declan all the best in their future endeavors.”

Democrat Aaron Wolf and Green Party candidate Matt Funiciello are also seeking the seat.
