Voters in suburban New York picked a Democrat to replace expelled Republican congressman George Santos on Tuesday, US networks projected, after President Joe Biden's party poured cash into TV ads to flip the seat in an election year.
CNN and NBC News both called the race in favor of Tom Suozzi, forecasting that he had defeated Republican Mazi Pilip in the election, which was marked by a heavy snowstorm across the district.
Tom Suozzi, a veteran politician who previously held the seat and quit to unsuccessfully run for New York state governor, will serve out the remaining 11 months of the scandal-plagued Santos's term in the House of Representatives.
The win chips away at the Republicans' narrow majority in the lower chamber of Congress.
"Thank God," Tom Suozzi said in a victory speech in Woodbury after the race was called. A crowd of supporters began chanting his name as protesters holding Palestinian flags briefly rushed to the stage, shouting "genocide."
"Despite all the lies... about Tom Suozzi being the godfather of the migrant crisis... despite the dirty tricks... we won."
New York City Mayor Eric Adams, a Democrat, said Tom Suozzi's victory "was good news for New York."
Biden, facing an uphill battle to get aid for key allies Ukraine and Israel approved in the Republican-led House, called to congratulate Tom Suozzi on his win Tuesday night, the White House said.
Mazi Pilip conceded during a speech in East Meadow: "We are fighters, I called my opponent and congratulated him," she said.
Pre-election polling had showed that the race was tight, with Democrats reportedly spending $14 million on advertising and the Republicans $8 million.
Aggressive attack ads were used by both sides, with Republicans seeking to paint Tom Suozzi as soft on illegal immigration, while Democrats characterized Mazi Pilip as against abortion rights.
Migration and abortion are central political issues as the United States limbers up for November's presidential election set to pit Biden against Donald Trump in a re-run of the 2020 contest.
One attack ad showed archive footage of Tom Suozzi apparently boasting that he fought to keep immigration enforcement officers out of Nassau County, where a large part of the congressional district is located, when he was the area's top elected official.
Anti-Pilip ads suggested she would seek a nationwide ban on abortions.
Deep snow in New York's third congressional district, which includes small parts of Queens and Long Island's wealthy North Shore in Nassau, threatened to deter voters as authorities warned against driving.
Both Tom Suozzi and Mazi Pilip's campaigns responded by offering a dial-a-ride service for voters, while there were media reports that the Republicans paid for plows to clear roads in areas sympathetic to the party.
Santos became only the third person to be ejected as a US lawmaker since the Civil War, in a rebuke previously reserved for traitors and convicted criminals.
He had won a House seat in 2022, helping the Republicans secure a tiny majority, but it quickly emerged that his backstory was largely a fabrication.
Santos, who has denied criminal wrongdoing, allegedly used donor money for Botox treatments and the OnlyFans porn website, as well as luxury Italian goods and vacations, according to the committee that investigated his conduct.
While the constituency backed Biden in 2020, Republicans took several seats in the area in 2022 and have an effective local operation to get out the vote.
