Anthony Constantino Claims Victory in NY-21 Midterm Nail-Biter: Inside the Dramatic North Country Battle for Elise Stefanik’s Open Seat

Republican Anthony Constantino has declared victory in the fiercely contested New York 21st congressional district election, securing 51.3% of the vote to hold off Democrat Blake Gendebien in unofficial midterm returns. Constantino garnered 139,786 votes compared to 133,708 votes for Gendebien, defending the expansive seat previously held by Republican Elise Stefanik.

Early returns from mail-in and early voting initially handed Gendebien an early lead. That advantage vanished rapidly as rural Election Day precincts began reporting their in-person totals late into the night.

The outcome caps an intense, high-dollar campaign that transformed a traditional conservative stronghold into a razor-thin battlefield stretching from the Mohawk Valley to the Canadian border.

How the Geographic Divide Decided the North Country

The geographic footprint of New York’s 21st District spans all or part of 15 counties, running from Fort Drum and Rome through Glens Falls to Plattsburgh. Winning such a sprawling jurisdiction required dominating distinct regional bases.

Constantino built his winning margin across the southern and western portions of the district, showing commanding strength in Fulton, Herkimer, Lewis, and Oneida counties. Those rural turnouts provided the raw cushion needed to overcome Democratic leads elsewhere.

Gendebien countered with notable strength in the eastern Adirondacks and the North Country borderlands. The Democratic challenger carried Clinton, Essex, and Warren counties, while also winning St. Lawrence County with 18,435 votes to Constantino’s 16,215 votes.

From Bitter Primary Infighting to the General Showdown

Constantino, the chief executive of Sticker Mule based in Amsterdam, ran an aggressive political outsider campaign to capture the nomination. He entered the general election after a bruising primary victory over Republican state Assemblyman Robert Smullen.

Clashing Personalities and Heated Debates

The road to victory was marked by sharp friction within the district’s Republican apparatus. At one point during the primary season, local party tensions boiled over when Constantino was removed from a St. Lawrence County Republican gathering following a verbal dispute with Smullen.

Despite early intra-party rifts, Constantino consolidated the conservative base after receiving an endorsement from Donald Trump. That backing helped shore up party loyalists ahead of a challenging general election blitz against Gendebien, a dairy farmer from Lisbon.

“The race for the seat currently held by Republican Rep. Elise Stefanik became one of the most closely watched congressional contests in New York, with national party organizations pouring resources into the district.”

The general election quickly escalated into a barrage of personal attacks and policy disputes. Debates centered heavily on campaign finances, candidate demeanor, and environmental allegations targeting Gendebien’s agricultural operations.

Busting the Myth of an Untouchable Stronghold

A widespread misconception across national political circles suggested that NY-21 was a permanent, unbreakable Republican fortress immune to competitive pressure. While the district maintains a documented conservative lean, the final margin demonstrated a far more complex reality.

Gendebien leveraged his rural dairy background to cut deep into traditional margins across northern counties. By forcing a finish decided by fewer than 6,100 votes out of more than 273,000 ballots cast, the race proved that local branding can still alter traditional party baselines.

Despite Constantino declaring victory late Tuesday night, the formal process remains underway. The New York State Board of Elections considers all election-night returns unofficial until every eligible absentee, affidavit, and military ballot is reviewed and officially certified.

💬 The razor-thin split across the North Country highlights just how volatile competitive congressional districts have become.
