Peter Oberacker wins Republican primary for New York’s 19th Congressional District

-endorsed state senator defeats Alexander Portelli and will face incumbent Democrat Josh Riley in the general election.

WHITE HOUSE — Donald J.Trump celebrated Peter Oberacker’s Republican primary victory in New York’s 19th Congressional District on a Truth Social post on June 23, 2026 at 8:52 PM EST.

Here is the full post (see truthsocial.com): “REPUBLICAN NOMINEE FOR NY-19 PETER OBERACKER WINS! ENDORSED BY PRESIDENT TRUMP! TRUMP VANCE MAKE AMERICA GREAT AGAIN!”

Oberacker, a New York state senator representing Delaware, Schoharie, Sullivan and Otsego counties as well as parts of Broome, Chenango and Ulster counties, defeated Alexander Portelli, a timber farm owner in Otsego County, to secure the nomination (see Google). The district stretches from Tompkins to Rensselaer County and includes the cities of Binghamton, Oneonta and Ithaca.

The victory sets up a general election clash with incumbent Democrat Josh Riley, who faced no primary challengers (see ballotpedia.org). Riley narrowly won the seat from Republican Marc Molinaro in 2024, a race Politico reported was the most expensive House contest in the country that cycle.

Trump’s endorsement played a central role in the primary. The post featured a campaign-style graphic showing Oberacker alongside Trump-Vance branding, underscoring the president’s direct involvement in the race. The outcome will test Trump’s influence in competitive congressional districts ahead of the midterm elections (see cityandstateny.com).

In the last 30 days, 128 of 646 Trump posts on Truth Social focused on the topic of elections, reflecting a sustained emphasis on primary contests and endorsements across the country.
