Several 2026 Senate contests remain highly competitive with polling averages showing margins of 1–3 points or less as of late October, including Iowa (Josh Turek vs. Ashley Hinson), Texas (James Talarico vs. Ken Paxton), Nebraska (Dan Osborn vs. Pete Ricketts), Kansas (Adam Hamilton vs. Roger Marshall), Maine (Troy Jackson vs. Susan Collins), and Alaska (Mary Peltola vs. Dan Sullivan under ranked-choice voting). National conditions, including low presidential approval and economic concerns, have narrowed traditional partisan gaps in these states. Heavy outside spending and final-week advertising target Iowa, Ohio, and Texas, while early voting and turnout patterns could influence close outcomes. Recent surveys from multiple pollsters show these races fluctuating within or near the 1% threshold, with forecasts rating four to seven contests as toss-ups or near-toss-ups.
