A Trump-endorsed businessman is on track to crush the party establishment’s pick in upstate New York, sending a clear message that Republican voters want fighters, not insiders.
Story Snapshot
- Anthony Constantino, backed by President Trump, is projected to defeat establishment favorite Robert Smullen in the NY-21 Republican primary.
- Constantino built a global business, self-funded his campaign, and pledged to donate his entire congressional salary to charity.
- Smullen had heavy support from the New York Republican Party machine, most county committees, and law-enforcement groups.
- The race shows Trump’s influence in the GOP is still strong and that grassroots conservatives can beat party elites.
Trump’s Chosen Challenger Breaks the Party Machine
CBS News and other outlets project that Anthony Constantino, a businessman and political outsider, is defeating State Assemblyman Robert Smullen in the Republican primary to replace Rep. Elise Stefanik in New York’s 21st Congressional District.[1][2]
Smullen entered the race with backing from the New York Republican Party and many local officials, but it was Constantino who carried the Trump banner and won over primary voters.[1][2]
Stefanik stayed neutral, underscoring how much this fight was really between the party machine and the Trump base.

The state Board of Elections data cited by the Associated Press showed Constantino leading Smullen by about 18 points with most precincts reporting.[2]
For conservative voters long frustrated by party insiders who talk tough but cave in Washington, this margin is more than just a win; it is a rebuke to the old guard.
The race became a test of Trump’s influence and of whether Republican voters would choose a loyal outsider over a well-connected establishment figure.[2][3]
Who Constantino Is: Business Builder and Trump Loyalist
Anthony Constantino is best known as the founder and chief executive of Sticker Mule, an e‑commerce company he started in 2010 that now operates in dozens of countries and employs well over a thousand people worldwide.[1][6][7]
His business success gave him the means to self‑fund his campaign, a decision he framed as a way to stay independent from lobbyists and party bosses.[5][10]
In his own campaign video, Constantino pledged to donate his entire congressional salary to charity, signaling that he does not plan to go to Washington to enrich himself.[10]
Constantino also built his identity around openly supporting President Donald Trump, even as many business leaders remained silent. After the 2024 assassination attempt against Trump in Butler, Pennsylvania, Constantino put a massive “Vote for Trump” sign on top of his company headquarters, sparking legal fights and local controversy.[1][5][6][8]
Trump later praised that sign on social media, saying Constantino “will never let you down,” and highlighted him as a “great guy” who stood firm amid pressure.[1][3]
Constantino even presented Trump with a seven‑foot bronze statue capturing the president’s raised fist after the attack, a symbolic move that drew national attention.[1]
Endorsements, Policies, and the Battle With the Establishment
Constantino’s campaign leaned hard into Trump’s support and the backing of key allies. Reports note that he is the only Republican in the NY‑21 field to receive Trump’s endorsement, and he also secured support from figures like Rudy Giuliani, Roger Stone, and Congressman Jim Jordan, who chairs the House Judiciary Committee and is one of Trump’s closest allies in Congress.[1][2][3]
These endorsements helped frame Constantino as the clear America First candidate in the race, in contrast to Smullen, who was heavily tied to the traditional party structure.[2]
On core issues, Constantino echoed Trump’s stance on border security and the cost of living. Coverage of the race notes that his platform calls for ending what Republicans describe as illegal immigration and making life more affordable in New York’s North Country.[1]
For voters in a rural, working‑class district facing high energy costs and inflation from years of reckless spending, that focus on affordability and border security goes straight to the heart of daily frustration.
Constantino’s promise to self‑fund, give away his salary, and challenge the status quo reinforced his outsider brand in the face of an entrenched party machine.[5][10]
Smullen’s Establishment Strength and Why It Fell Short
Robert Smullen did not run as a moderate; he is a Marine veteran with 24 years of service, including combat tours, and has served in the New York State Assembly since 2018.[9][15]
He secured endorsements from the New York State Republican Party, most county party committees, the Conservative Party line, state troopers and police unions, and gun rights groups such as the Rifle and Pistol Association.[2][9]
Smullen also points to past appointments by Presidents George W. Bush and Donald Trump to national commissions, signaling his long-standing presence within the Republican establishment.[9]

Despite these credentials, Smullen’s institutional backing did not overcome grassroots anger at party elites. In debates and on social media, his allies tried to cast Constantino as “mentally unfit” and as someone trying to “buy the seat” with personal wealth, and they highlighted that Constantino had been registered as a Democrat until 2024.[2][8][9]
But neither side produced clear primary-source records to settle many of the sharper accusations, and voters were left to judge character and alignment with Trump’s agenda on their own.[9][11]
The projected outcome suggests GOP voters cared more about loyalty to Trump and independence from the party machine than about insider endorsements.
What This Means for Conservatives and Trump’s GOP
This primary fits a broader pattern in which Trump‑backed challengers have defeated establishment Republicans who hesitated to embrace the president’s agenda.[3][20][22]
National reports have tracked dozens of races in which Trump-endorsed candidates won or advanced in Republican primaries, often unseating critics and signaling that the base still wants America First policies.[3][20][21]
While there have been a few races, such as a recent Iowa governor’s primary, in which Trump’s pick lost, the overall record shows that his endorsement remains a powerful force in Republican politics.[18][22]
For conservatives, Constantino’s projected win in NY‑21 sends several clear signals. First, Republican voters in a swing‑sensitive region are still willing to back a Trump‑aligned outsider over a polished insider when given a real choice.[1][2]
Second, business leaders who openly support Trump and refuse to bow to woke pressure can succeed with the base, especially when they put skin in the game and reject special interest money.[5][6][10]
Third, the party establishment cannot assume it can handpick nominees without facing serious grassroots pushback.
As the Trump administration’s second term continues, races like this will shape whether the next Congress backs strong border security, energy freedom, and a real rollback of federal overreach—or slides back toward business‑as‑usual politics.
