Senate Shifts: Democrats Take 28 Seats as Republicans Retain 7 in 2026 Midterms

The United States Senate has changed hands following the 2026 midterm elections, with the Democratic Party securing a decisive majority. The results indicate that Republicans have lost at least seven seats, a significant shift in power that marks a major defeat for the party that held the chamber's leadership. This loss of the majority alters the balance of power in Washington, placing the Senate firmly in Democratic control for the next two years. The outcome reflects a broader trend seen in the election results, where voters signaled a desire for change in the direction of the government. The Senate will now operate under a new dynamic as the incoming Congress prepares to convene in January.

Republican Senator John Thune of South Dakota is expected to be reelected as the party leader, a decision that will be formalized during a closed-door vote in the Old Senate Chamber. Thune, who replaced Senator Mitch McConnell as leader in early 2025, is running unopposed and is viewed as having widespread support among his colleagues. Despite the recent electoral setback, many within the Republican conference believe Thune is best positioned to guide the party through its new role as the minority. He has been noted for his collaborative approach and for maintaining close relationships with the rank and file, a strategy that distinguishes his leadership from his predecessor. The leadership elections are scheduled to take place on Tuesday, a day that also serves as the start of freshman orientation for the new members of Congress.

However, not all Republican senators are comfortable with the immediate ratification of the current leadership. Senator Ron Johnson of Wisconsin has argued that the defeat demands a period of soul-searching before the party moves forward. Johnson circulated a letter to the conference asking for a delay in the leadership elections to allow for a more thorough discussion of the party's future direction. He emphasized that the party cannot simply continue on business as usual after such a significant loss of seats. Senator Josh Hawley of Missouri echoed these sentiments, describing the election as an incredible repudiation of the focus of the previous Congress. Hawley cited reductions to Medicaid and rural hospital funding in the recent tax cuts bill as a key factor in the party's loss, noting that he has not yet heard an acknowledgement of these issues from leadership.

The upcoming leadership vote will be held in the small Old Senate Chamber, just down the hall from the main floor where the Senate meets. The timing of the vote is seen by some as strategic, as it coincides with the arrival of new Republican senators who are in Washington for their orientation. Oklahoma Senator Jim Lankford supports holding the election on this day, arguing that it is the appropriate time to establish leadership for the new conference. He described the role as complicated and noted that few members are eager to take on the job. South Dakota Senator Mike Rounds agreed, stating that most senators are ready to move forward and that having leadership in place is essential for the party to begin its work in the minority.

President Donald Trump has offered his support for Senator Thune, describing him as a very fine man during a briefing on Monday. The President stated that the decision on the party leadership is ultimately up to the Senate, though he has hosted Thune and his family at the White House recently. Trump's endorsement adds weight to Thune's position, although the final decision rests with the Republican senators. The President has also indicated that the administration will work with the new Senate majority, though the specifics of this collaboration remain to be seen. The relationship between the White House and the Senate leadership will be a critical factor in the legislative agenda of the coming year.

Two Senate races in Alaska and Mississippi remain uncalled, with the outcomes potentially affecting the final composition of the Republican conference. In Alaska, Republican Senator Dan Sullivan faces an uncertain future as the race remains close. In Mississippi, Republican Senator Cindy Hyde-Smith is also in a tight contest. These two races could further deplete the Republican numbers if the Democrats secure victories, making the path to rebuilding the party's strength even steeper. Republican Senator Mike Lee of Utah has suggested that any leadership contest should wait until these races are decided, arguing that the party needs a clear picture of its size before choosing its leader. The outcome of these two states will be closely watched as they provide the final data points for the Senate's new balance of power.

The shift in the Senate means that Democrats will now hold the gavel and control the legislative agenda. This change allows the party to pursue its priorities, including oversight of the administration and potential changes to health care and cost of living measures. The Democratic leadership will likely move quickly to set a tone for the new Congress, emphasizing their mandate from the voters. The Republican conference, now in the minority, will have to adjust its strategy to focus on oversight and building a base of support for its key legislative goals. The transition of power is expected to be smooth, with both parties working to finalize the logistics of the new session.

Senator Thune is expected to emphasize his party's achievements in the last two years, including the passage of the tax and spending cuts legislation and efforts to streamline the annual spending process. He will likely argue that the Republican conference has made significant progress despite the challenges it faced. The leader will also highlight his willingness to work with Democrats, a stance that he has maintained during his time in the majority. This approach is designed to reassure colleagues that the party can still be effective in a minority position and that it can achieve meaningful results through collaboration. The next Congress will be a test of this new dynamic.
