Registered nonpartisan Dan Osborn tried to unseat a Republican U.S. Sen. Deb Fischer in 2024. Osborn outperformed President Donald Trump and gave Fischer an unexpectedly close race, with the senior U.S. senator for the Cornhusker State winning by 6.7 percentage points in the end. The Trump-Harris margin was larger in all but two counties (Boyd and Red Willow).
The following represents how much Osborn performed better than Vice President Kamala Harris over Trump by county. Counties in purple are counties where the Fischer-Osborn margin was narrower than Trump-Harris, and by how much.
