Several Senate contests remain highly competitive with recent polling averages showing margins under or near five points in states including Iowa, Ohio (special election), Texas, Maine, Alaska, and Nebraska. Democrats benefit from an expanded battleground map, strong recruits such as former Gov. Roy Cooper in North Carolina and Mary Peltola in Alaska, and voter concerns over affordability and the broader midterm environment under a Republican administration. Republicans defend more seats overall but face defensive spending needs in traditionally red states where Democratic challengers have closed gaps sharply in the past month. Fundraising edges, like Jon Ossoff’s in Georgia, and late-cycle advertising could still shift outcomes in these toss-up and lean races before November 3.
