What

The 2026 U.S. House election will determine whether Republicans retain or lose their narrow majority ahead of the Feb 1, 2027 count.

Context

Republicans entered 2026 with a 220-215 functional majority (plus vacancies), but face a 6.5-point swing toward Democrats since 2024.

Stakes

A Democratic House majority would shift legislative power, potentially blocking Republican initiatives and altering the agenda for the remainder of the presidential term.

Note: The 203-207 outcome requires Republicans to lose only 13-17 seats from their current ~220, which contradicts the consensus of 20-28 seat losses predicted by major forecasting models.
