**Maine’s 2026 Senate contest between incumbent Republican Susan Collins and Democrat Troy Jackson registers as the closer race in recent polling averages and forecaster ratings.** Multiple surveys through early October show statistical ties or margins of 1–4 points, with results alternating between candidates and frequent undecided shares that keep the outcome within the margin of error. Texas’s open-seat matchup between Democrat James Talarico and Republican Ken Paxton shows a steadier Democratic edge of 2–6 points across recent Times/Siena, Fox, and Marist polls, producing larger average leads despite the state’s Republican lean. Maine’s tighter spreads reflect the race’s toss-up status, independent-voter dynamics, and Collins’s established position, while Texas polling indicates a more decisive tilt even amid elevated spending and candidate controversies. These patterns underpin trader assessments that Maine remains the narrower contest heading into November.
