Independents Drive Democratic Midterm Lead

A September Economist/YouGov poll finds Democrats ahead 51%–39% among likely voters, with independents favoring Democratic House candidates roughly 54% to 27%. The gap is much smaller among all registered voters and reverses among less‑definite (non‑likely) voters, suggesting turnout composition is the decisive factor. — If independents remain mobilized and probable voters actually turn out at the measured rates, the 2026 midterms could tilt substantially toward Democrats even if the broader registered‑voter picture looks closer.
