Mikie Sherrill’s resignation slightly widens Speaker Mike Johnson’s already narrow House majority, leaving the chamber at 219 Republicans, 213 Democrats and three vacancies. That slim margin still requires near-unanimous GOP support on close, party-line votes, though it provides a bit more leeway for absences. Several special elections — in Tennessee next month, a Texas runoff in late January and a special to replace Sherrill early next year — could further reshape the balance. Historically, margins this tight are uncommon and can complicate leadership’s ability to pass contested legislation.
Sherrill’s Resignation Gives Speaker Johnson a Slight Breather in a Razor‑Thin House Majority

House Speaker Mike Johnson gained a small but meaningful cushion in his narrow majority after Democratic Rep. Mikie Sherrill resigned following her election as New Jersey governor. Sherrill stepped down two weeks after her victory and about two months before taking office, creating another temporary vacancy that eases immediate pressure on Republican leaders — if only modestly.
Current math and what it means
The House now counts 219 Republicans, 213 Democrats and three vacant seats. If all 432 seated members were present and voting, a majority would be 217. With 219 Republicans on the roster, Johnson can only afford very few defections on party-line votes — at most two GOP members if every other member votes — which keeps the conference dependent on near-uniform unity.
Upcoming special elections
The balance could shift again in the coming months. A Republican-leaning district in Tennessee is scheduled for a special election early next month. In late January, two Democrats in Texas will face each other in a runoff to fill another vacant seat. The special election to replace Sherrill is expected to take place early next year. Each contest will affect the narrow working majority and the flexibility Republican leaders have to pass contested measures.
Historical context
Sustaining such tight margins is unusual in modern times and echoes rare moments in U.S. history — most notably in the early 1930s. After the 1930 elections, party splits were similarly narrow, and shifting vacancies and special elections at the start of that period changed control of the chamber. Historical records also point to other close divisions, such as the early 20th-century Congresses where third-party members played decisive roles in speaker elections.
Implications for legislation
Johnson and House Republicans have at times used their slim majority to pass major bills, but the narrow margin makes governing and coalition-building difficult. For example, GOP leaders lost two Republican votes on the final passage of a large tax-and-spending package this year, underscoring how a handful of defections or absences can alter outcomes. With several special elections ahead, House control and the prospects for contentious legislation remain in flux.
