Republicans remain confident they can hold power, and Senate Majority Leader John Thune even said in a recent fundraising email that an expanded map could backfire on Democrats. Democratic Senate nominee Adam Hamilton hopes that voters’ struggles during Trump’s presidency will be enough to help him unseat Republican Sen. Roger Marshall. But national Democrats back independent Dan Osborn, a former labor union chief, as their choice to unseat Republican Sen. Pete Ricketts. Osborn lost to Republican Sen. Deb Fischer by 7 points in 2024. To be sure, Osborn has not said he’d caucus with Senate Democrats.
