Summary

Democrat Adam Gray’s victory in California’s 13th district tightens the Republican House majority to 220–215, marking the narrowest margin since the Hoover administration.

The GOP majority is expected to shrink to 217–215 in early 2025 due to Gaetz’s resignation and Stefanik and Waltz’s anticipated departures for the Trump administration.

With this slim majority and internal party divisions, House Republicans face significant challenges in advancing their legislative agenda under the incoming Trump presidency.
