Jacky Rosen Holds Off Sam Brown in Nevada, Keeping a Democratic Senate Seat

Senator Jacky Rosen, a Democrat, will narrowly hang on to her Nevada Senate seat, according to The Associated Press.

For both parties, it was an unexpected nail-biter. Her victory, while a bright spot for Democrats in an otherwise grim Election Day outcome, highlighted broad rightward shifts in her state and around the country.

Several of her fellow Democratic incumbents, like Senator Jon Tester of Montana, were ousted; Ms. Rosen will head back to Washington for her second term now in the minority. President-elect Donald J. Trump has so far won all six of the presidential battlegrounds that have been called — including Nevada, which went red for the first time since 2004 — while flashing strength in traditionally blue strongholds.

“Thank you, Nevada!” Ms. Rosen posted on X after the race was called. “I’m honored and grateful to continue serving as your United States Senator.”

Mr. Brown’s campaign did not immediately respond to a request for comment. Mr. Brown posted on X just minutes before the race call early on Saturday morning, writing that Nevada’s still counting thousands of ballots days after the election was “unacceptable,” and that “we deserve to know election results within hours, not a week later.”

Ms. Rosen, a former computer programmer and synagogue president, was seen as vulnerable, given Nevada’s swing state status. A political newcomer when she was asked by Senator Harry M. Reid, the influential Democrat who died in 2021, to run for office, Ms. Rosen cut a low profile as she cultivated a bipartisan, pragmatic image. That made it difficult for opponents to attack her, but also presented a challenge to Ms. Rosen’s efforts to define herself apart from a deeply unpopular Biden administration, especially to an electorate that is more transient than that of other states.
