More than a tenth of Congress has indicated plans to vacate their seats following the 2026 midterm elections, driven by factors such as redistricting, retirements, and aspirations for other political offices. This unprecedented rate of departures raises questions about the future landscape of American politics.
Why It Matters
The significant turnover in Congress reflects a volatile political climate and may lead to shifts in party dynamics as seasoned politicians give way to new leadership. This could impact key legislative agendas and voter sentiments as midterm elections approach, particularly with narrow margins controlling both the House and Senate.
Key Developments
- As of December 2025, 54 members of Congress, including 10 senators and 44 representatives, are either retiring or seeking different offices.
- Notable retirements include veteran figures like California Rep. Nancy Pelosi and Kentucky Sen. Mitch McConnell.
- A significant number of lawmakers are pursuing gubernatorial roles, with 15 aiming to become governor while 13 intend to transition from the House to the Senate.
- The Senate is experiencing its highest turnover since 2012, reinforced by a record number of announcements of departures so early in the election cycle.

Retirements and Aspirations
This wave of departures includes 25 officials choosing to retire from public office, while others are actively campaigning for different positions. For instance, Texas Republican Rep. Chip Roy has his sights set on becoming the state’s attorney general. Both Tennessee’s Marsha Blackburn and Colorado’s Michael Bennet have indicated they will resign from their Senate seats should they secure a gubernatorial win, adding further complexity to the political landscape.
Changes in Leadership
With Pelosi’s announcement following the successful off-year elections for Democrats in November 2025, a generational shift appears imminent, as older party leaders opt to hand over responsibilities to younger candidates such as Senators Dick Durbin and Jeanne Shaheen, along with Representatives Jan Schakowsky and Dwight Evans.
Impact of Redistricting
The current reshuffling of congressional boundaries, spurred by both Republican and Democratic-led redistricting efforts, has accelerated lawmakers’ decisions to step down or seek other offices. The Supreme Court’s recent decision to implement Texas’ new congressional map for the upcoming elections has contributed to a flurry of retirements ahead of key deadlines.
Record Departures in the Trump Era
Since President Trump’s inauguration in 2017, over 140 lawmakers have departed Congress through retirement. With nearly two-thirds of the current Senate and 44% of the House composed of members who began their tenures during Trump’s administration, the potential consequences of such significant turnover could reshape party dynamics and legislative priorities moving forward.
Context & Previous Events
Recent years have witnessed fluctuations in Congressional representation, with the Trump era marking a notable period of political realignment. During this time, 900 individuals have served in Congress, among them 132 senators and 751 representatives, including those who held positions in both chambers. This backdrop of shifting political fortunes underscores the heightened stakes as lawmakers prepare for the 2026 midterms.
