Democrats control Congress: What it means for oversight and the 2028 race

Democrats secured majorities in both the U.S. House and Senate following the midterm elections held on November 3, 2026. According to results compiled by Ballotpedia, Democrats picked up at least 43 House seats and seven Senate seats. As of 4 p.m. EST on November 6, the House majority stood at least 250 to 157, while the Senate majority was at least 54 to 44. This sweep marks a significant shift in power, with Republicans suffering a net loss of at least seven Senate seats, a result that places this election in the top 20% of years for seat swings against a president's party.

The immediate implication of this control is a surge in oversight activities. Rep. Jim Jordan of Ohio, who was elected as the House Republican minority leader, warned of the coming Democratic efforts on oversight. He stated that numerous investigations of the Trump administration are expected. Jordan, who serves as chairman of the House Judiciary Committee, emphasized his battle-tested experience on the oversight front, noting that he knows the Democrats' playbook. He argued that the Republican job cannot be merely to spotlight the new Democratic Party, but rather to focus on offense to win future elections.

In the Senate, the dynamics of leadership are already shifting. Sen. Bernie Sanders of Vermont announced he would not support Sen. Chuck Schumer for re-election as Democratic majority leader. Sanders, joined by Sen. Elissa Slotkin of Michigan, argued that there is a need for a new generation of leadership. Slotkin stated that she wants to see potential leaders present a full plan about the priorities for the new majority, calling her position a no until she sees such a plan. This move signals a vigorous debate about the party's direction and future, particularly among the progressive wing which has been pushing for change.

The race for Senate leadership is heating up with several names in the mix. Sen. Chris Van Hollen of Maryland, who has previously considered a run for president in 2028, is now also considering a run for Senate leader. Van Hollen said he is in the process of calling his colleagues to gauge support. Meanwhile, Schumer, who is 75, has shown few signs of stepping aside, especially after leading his party to power. He told AP that the focus has got to be on getting things done. New York Sen. Kirsten Gillibrand, chair of the Democratic Senatorial Campaign Committee, gave a full-throated defense of Schumer, stating that the caucus is grateful for his work.

On the Republican side, Senate Republicans reelected South Dakota Sen. John Thune as leader of the GOP conference. Thune, who replaced Mitch McConnell in early 2025, was running unopposed in the secret ballot election. However, the re-election came after three separate meetings where Republicans vented frustrations over their steep losses. Sen. Jim Justice of West Virginia noted that while the current leadership did not cause the problem, there was a legitimate argument for changing course if the losses were as bad as they were. Sen. Josh Hawley of Missouri walked out of one meeting, stating that if leadership does not think they need to change course after losing seven Senate seats, they are on the wrong planet.

The House Republican conference also underwent a leadership shakeup. Rep. Jim Jordan defeated Rep. Steve Scalise of Louisiana in a 106 to 73 vote to become the minority leader. Jordan, a co-founder of the House Freedom Caucus, appealed to those looking for new leadership after the election debacle. Scalise, who had served in key leadership positions since 2014, emphasized his fundraising prowess, noting he raised $67.9 million for the midterms. However, the majority of Republicans opted for Jordan's hard-hitting style. Other leadership positions, including whip, are still up for grabs, with Reps. Tom Emmer of Minnesota and August Pfluger of Texas vying for the role.

The sweep in Congress is part of a broader Democratic victory across the country. Democrats won a plurality of state government trifectas and state legislative chambers. According to Ballotpedia, Democrats had won 22 of the 36 gubernatorial races, with Republicans winning 12. This marks the first time since before the 2010 elections that Democrats have won a majority of governorships. The party also gained control of 12 state legislative chambers, with zero changes going to Republicans. This state-level control provides a foundation for the federal majority, allowing Democrats to push agendas from the ground up.

The composition of the new House includes several upset victories that highlight the reach of the Democratic campaign. Rep. Suzan DelBene, chair of the Democratic Congressional Campaign Committee, noted that the victory was impressive because of how far Democrats reached into deep red territory. In North Carolina's 9th district, Democrat Richard Ojeda defeated seven-term Republican Rep. Richard Hudson. Ojeda, a former Army major, capitalized on his background as a social media phenomenon. In Wisconsin's 1st district, Democrat Mitchell Berman, an emergency room nurse, defeated Republican Rep. Bryan Steil by nearly four points. Berman's victory is notable as no Democrat had won that seat since 1993.

These upsets extend to other districts as well. In Colorado's 5th district, Democrat Jessica Killin, a former Army captain, defeated Rep. Jeff Crank. Killin ran as a moderate, tapping into voter anger in a district home to NORAD and the Air Force Academy. In Nevada's 2nd district, Democrat Teresa Benitez-Thompson made history as the first Democrat to win the seat. Her victory means that for the first time ever, all of Nevada's congressional seats will be held by Democrats. In Texas, Democrat Katy Padilla Stout won the 23rd district by eight points, a district that had not elected a Democrat since 2012. These wins suggest that the Democratic coalition is broadening its appeal beyond traditional urban centers.
