WATERTOWN — Elise M. Stefanik has won the Republican primary in the race for New York’s 21st Congressional District.
Her opponent for the Republican nomination, Matthew A. Doheny, still will be on the ballot in the November general election, as he has been endorsed by the state Independence Party. Ms. Stefanik also has been endorsed by the state Conservative Party.
They will face Democrat Aaron G. Woolf, a documentary filmmaker with a home in Essex County, and Green Party candidate Matthew J. Funiciello, a bakery owner and political activist from Glens Falls.
In her victory speech, Ms. Stefanik pledged to bring “common sense, Main Street solutions” to Washington, D.C., and said she was willing to work with “anyone, anywhere” to accomplish that feat.
Describing herself as a bridge-builder, Ms. Stefanik forecast a win in the general election.
“We’re going to win this November,” she told supporters at the Queensbury Hotel in Glens Falls.
At midnight Tuesday, Ms. Stefanik led Mr. Doheny 14,909 to 10,297, garnering 60 percent of the vote.
The race was contentious from the beginning, but the tension between Ms. Stefanik and Mr. Doheny increased in the last few weeks, with nearly $1.2 million in outside money pouring into the district. American Crossroads, a GOP super PAC associated with Karl Rove, spent more than $800,000 on television ads and mailers opposing Mr. Doheny.
In his concession speech, Mr. Doheny said the involvement of super PACs from outside the district heralded a new age of politics, and he attributed his loss to being outspent “six, seven to one.”
“My opponent had a good night; Karl Rove had a good night. That’s just the reality,” Mr. Doheny told supporters gathered in Watertown.
Ms. Stefanik declared her intent to take on U.S. Rep. William L. Owens, D-Plattsburgh, in August. Mr. Owens announced in January that he would not seek re-election.
Mr. Doheny, an investment fund manager from Watertown, ran against Mr. Owens in 2010 and 2012 and entered the race after Mr. Owens announced his retirement from politics.
After graduating from Harvard in 2006, Ms. Stefanik worked in the George W. Bush White House in the office of Domestic Policy Council staff and the chief of staff’s office, where she said she worked on economic and domestic policy issues. She also worked as director of debate prep for Republican vice presidential nominee Paul Ryan. Mr. Ryan campaigned with Ms. Stefanik in Watertown in early June.
The 21st Congressional District, which contains all or part of Clinton, Essex, Franklin, Fulton, Hamilton, Herkimer, Jefferson, Lewis, Saratoga, St. Lawrence, Warren and Washington counties, is one of the largest districts east of the Mississippi River.
Since 2009, it has been represented by Mr. Owens, who won a special election that year to replace Rep. John M. McHugh after President Barack Obama appointed Mr. McHugh to be secretary of the Army.
Mr. Woolf issued a statement reacting to the news of Ms. Stefanik’s win and said he was looking forward to continuing the race.
“I look forward to a spirited and ongoing discussion of the issues with my opponents. Since entering this race, I have been focused on listening to the voters and presenting our agenda for creating jobs and ensuring long-term growth for our economy. I intend to continue this productive discussion throughout the general election,” Mr. Woolf said in an emailed statement. “As someone who has spent his career chronicling the consequences of government decisions, I’m all too aware of the costs of shortsighted policies and partisan gridlock. We need citizen representatives, unencumbered by corrupting influences and insider politickin — only then can we address the toxic inaction of the U.S. House of Representatives.”
