Background

Anthony Constantino is the CEO and founder of Sticker Mule, an online printing company he established in 2010, headquartered in Amsterdam, New York. He is a political outsider with no prior elected office; his public profile before entering politics was built entirely around his business career. 2412

Constantino attended Stonehill College and later Rensselaer Polytechnic Institute (RPI), but left RPI without graduating to work at the family business, according to Mother Jones. 6 He was born and raised in the suburbs of Amsterdam, though WAMC has also identified him as being from Edinburg. 1418

Constantino won the Republican nomination for New York's 21st Congressional District in the June 23, 2026 primary and received an endorsement from President Trump. 62021 He is running for an open seat vacated by retiring incumbent Elise Stefanik. 9 He has pledged to spend approximately $2.6 million of his own money on the race. 22

Constantino drew public attention prior to his candidacy for erecting a 100-foot pro-Trump sign at his business and for his outspoken support of the former president on social media. 229 His campaign has also been marked by social media controversies and at least one lawsuit. 23
