Does the 2026 wave predict 2028?

An unusually large midterm swing (roughly a 15‑point House popular‑vote shift and big gains in Senate, governors, and House seats) may be more than a momentary rebuke: it could represent a durable realignment if it reflects widespread repudiation of a lame‑duck president rather than short‑lived turnout shocks. Comparing past large midterms (1946, 1966, 1974, 1994, 2006, 2010) helps assess whether such waves presage multi‑year party advantage or instead normalize quickly. — If true, the claim alters expectations for campaign strategy, judicial appointments, federal–state power balance, and 2028 forecasting—shifting where parties invest and how institutions prepare.
