How does an AARP poll describe older voters in Ohio?
Older voters still favor Republicans despite an overall Democratic lead in the state. Trump approval has dropped sharply among this group.
September polling generally shows an anti-Trump environment and a Democratic congressional-ballot advantage near nine to 11 points, including NBC's 52%–43% average. Historical analyses warn Democratic Senate support may be overstated, and expert race ratings disagree with quantitative models. Disputed methodologies, small samples, third-party candidates, prediction markets, and unstable likely-voter assumptions make the apparent edge difficult to quantify.
