Ms. Rosen, the low-key incumbent, hung on, but the race was closer than expected amid President-elect Donald J. Trump’s strength.

Incumbent Sen. Jacky Rosen (D-NV) defeated Republican challenger and army veteran Sam Brown in the Nevada Senate race, ensuring a second term as the state’s junior senator next Congress. The race was much closer than Rosen would have liked and took days count.

Jacky Rosen won reelection in the battleground state of Nevada, overcoming a challenge by Republican Sam Brown. Rosen, who was first elected in 2018, used her sizable cash advantage over Brown to run ads framing her opponent as an anti-abortion extremist and political carpetbagger who only moved to the state in 2018.
