NEW YORK — In a surprising twist in upstate New York's political landscape, the Democratic Party may be on the verge of capturing a House seat in a district that President Donald Trump won by a substantial 20-point margin in 2024. An internal poll shows Democratic contender Blake Gendebien nearly neck and neck with his Republican opponent, Anthony Constantino, trailing by just one percentage point at 45-44, with 11% of voters still undecided.

The district, currently held by the outgoing Republican Rep. Elise Stefanik, saw Constantino secure the GOP nomination after a contentious primary battle with state Assemblymember Robert Smullen. Constantino, who is the CEO of a sticker company, infused his campaign with $10 million of his own money and received a crucial endorsement from Trump. His campaign antics, including releasing a rap album praising Trump and engaging in aggressive tactics against his primary opponent, have marked his run with controversy.

Blake Gendebien, a local dairy farmer, appears to be benefiting from the Republican infighting. Polls conducted after a detailed messaging campaign showed Gendebien moving ahead of Constantino 49-40 among likely voters, a significant shift suggesting the Democratic message is resonating with the district's electorate.

The district spans from the northern Catskills to the Canadian border, a traditionally conservative stronghold where 58% of voters supported Trump in the recent presidential election. However, the dynamics of the upcoming general election could still see shifts, especially with the possibility of a three-way race if Smullen, who has the backing of the state’s Conservative Party, decides to continue his candidacy.

Adding to the Republican woes, internal disputes have deepened, highlighted by a defamation lawsuit between Jerry Kassar, the Conservative Party chair, and Constantino. This legal battle stems from allegations of life-threatening behavior, further stirring the political pot in NY-21.

Battleground New York, a group dedicated to flipping competitive House seats, notes that the bruising GOP primary has positioned the Democrats advantageously. "Republicans in NY-21 couldn't afford a messy primary, and they got one anyway," said Andrew Grossman, a spokesperson for the group. "They spent the primary proving they can't stand each other, now offering voters a choice between the disliked party nominee and the controversial candidate."

As the district braces for what could be a pivotal election, all eyes are on Smullen's next move, which could further complicate or clarify the race dynamics. With the general election looming, NY-21 may indeed be a bellwether for the shifting political allegiances in upstate New York.
