2018 midterm elections
Democrats won control of the U.S. House and made gains in state legislatures. The wave election forced both parties to rethink leadership and messaging.
Democrats elected Nancy Pelosi as speaker; Republicans adjusted state-level strategies.
The election showed how midterm waves can change governing agendas even when the presidency stays in the same party.
Utah's 2026 election produced a smaller Republican majority, prompting caucus leadership changes similar to how wave elections force parties to respond.
