Trump Endorsement Sparks Fierce Republican Primary for NY-21 Seat
The 2026 race for New York’s 21st Congressional District has evolved into a personal Republican primary between Assemblymember Robert Smullen and businessman Anthony Constantino. While Constantino holds Donald Trump’s endorsement, Smullen maintains support from the state’s Republican and Conservative party machines, creating a rift that some analysts say could benefit Democrats.
Why are Robert Smullen and Anthony Constantino competing for NY-21?
The vacancy follows President Donald Trump’s nomination of Rep. Elise Stefanik to serve as U.N. ambassador. Assemblymember Robert Smullen and Anthony Constantino, CEO of the Amsterdam-based company Sticker Mule, are now vying for the seat.
Smullen argues his government experience and familiarity with the district make him the best fit. In an interview with Spectrum News 1, Smullen identified federal oversight of state energy policy, affordability, and securing the northern border with Canada as his top priorities.
Constantino emphasizes his background as a business owner to argue he can attract manufacturing jobs and economic development to the region. He has advocated for expanded internet access across the North Country and promoted the use of automation in manufacturing.
How does the Trump endorsement affect the race?
Donald Trump endorsed Constantino in April, citing support from allies Rudy Giuliani and Roger Stone. Constantino described this as “the greatest endorsement you could get,” while contrasting his standing with Smullen’s ties to “party insiders.”
Smullen maintains the support of the state’s Republican and Conservative party machines. He noted that every committee that has held an endorsement vote across the 15 counties has voted for him.
Smullen also pointed to his own history with the former president, stating he was appointed by Trump in 2018 to the President’s Commission on White House Fellows. He has suggested Trump may have received poor advice from his inner circle regarding the current endorsement.
Could internal GOP infighting lead to a Democratic victory?
The current tension has drawn comparisons to the 2009 special election in the then-23rd Congressional District. In that instance, Republican nominee Dede Scozzafava suspended her campaign and endorsed Conservative Party candidate Doug Hoffman, which allowed Democrat Bill Owens to win the seat.
Grant Reeher, a political science professor at Syracuse University, said Democrats should not be counted out. Reeher stated that if the Republican candidates “run against themselves,” a Democratic candidate who avoids moving too far left could potentially “run up the middle” to win.
Smullen has stated he will remain on the Conservative line in November. Constantino has dismissed the possibility of a split, suggesting that voters will “do the right thing.”
Where do the candidates agree?
The candidates show little disagreement regarding U.S. policy toward Iran. Smullen, a veteran, stated he supports Trump’s current approach to the conflict, expressing optimism that a resolution would ease energy shortages and costs.
Constantino also expressed trust in Trump’s judgment, calling him the “best decision-maker we have” regarding peace and leadership. Despite this policy alignment, the candidates remain personally estranged; Smullen recently declined to shake Constantino’s hand at a debate, citing the businessman’s campaign tactics.
