Democrat Laura Gillen has defeated U.S. Rep. Anthony D’Esposito on Long Island, unseating the Republican after one term and rolling back recent GOP gains in New York City’s suburbs

Gillen’s win puts a dent into Republicans’ recent gains across Long Island. Last year, Republicans won the Suffolk County executive seat. And D’Esposito’s 2022 victory flipped a seat that Democrats had held for nearly three decades.

Democrat Laura Gillen was projected to win a tight race on Long Island, according to NBC News, one of the hotly contested New York congressional districts that could determine the balance of power in the House of Representatives.
