Survey shows Anthony Constantino leading Blake Gendebien in race for New York’s 21st Congressional District

A survey cited by New York Post Politics on August 19 reported that Anthony Constantino leads Blake Gendebien in the race for New York’s 21st Congressional District, the seat currently held by Rep. Elise Stefanik (R-NY). The Post said the poll found Constantino at 50% support compared with 40% for Gendebien, with 10% undecided.

The district-level contest is framed as the next step after Stefanik’s current term, with voters choosing between Constantino and Gendebien for the seat. The Post’s description of the candidates places Constantino as the leading figure in the survey and characterizes Gendebien as a dairy farmer.

According to the same report, the poll results suggest that the race remains competitive but that Constantino has an advantage large enough to separate the two candidates by 10 percentage points. The presence of an estimated 10% undecided group indicates that the outcome could shift if undecided voters consolidate around either candidate.

Election polling in congressional races is often used by campaigns and media to gauge name recognition and issue salience, but the practical effect depends on the poll’s methodology, sample size, and field dates. The Post report did not, in the information provided here, specify those technical details.

For voters in the 21st district, the choice centers on who will represent them in Congress following Stefanik’s seat. The congressional agenda that would follow a change in personnel would be determined by the winner after the election, including how the new member aligns on federal budgets, enforcement priorities, and other federal policy questions that routinely come before the House.

Neither the Post report nor any other primary record provided in the materials here confirms further details about the polling firm, question wording, or the dates the survey was conducted, all of which would typically be needed to fully assess reliability and compare it to other polling in the same race.

With Election Day approaching, parties and candidates are likely to continue focusing on turnout and persuasion among voters who are not committed, particularly given the reported 10% undecided share in the survey cited by the Post.
