2026 US Midterm Election Results: Democrats Win Control of House and Senate

Democrats secured control of both chambers of Congress in the 2026 midterm elections, successfully flipping seven seats in the U.S. Senate to reach a total of 54, according to NBC News projections. The party also surpassed the 218-seat threshold required to command a majority in the House of Representatives, effectively shifting the balance of power in Washington.

Senate Gains and Shifts in Power

The Democratic majority in the Senate was built on a series of victories in states previously held by Republicans. NBC News reported that Democrats successfully flipped seats in North Carolina, South Carolina, Kansas, Texas, and Iowa. These gains allowed the party to move past the 51-seat threshold needed for control, bringing their total to 54 seats. The election cycle saw 35 Senate seats up for contest, with Democrats winning a majority in the chamber, according to data from The Guardian.

House Majority Thresholds

In the 435-member House of Representatives, Democrats reached the 218 seats necessary to secure a majority. The Guardian noted that Republicans entered the election defending their narrow hold on the chamber, while Democrats began with 212 seats. With all 435 seats contested, the shift ensures that Democrats will hold the majority in the House and influence on revenue bills and federal oversight for the next two years.

Demographic Trends Shape Party Support Across Regions

Analysis of the 2026 results indicates distinct voting trends across demographics and regions. According to reporting from DW, Democrats found their strongest support among younger voters, with 75% of those aged 18 to 24 casting ballots for the party. Urban and suburban voters also leaned Democratic, with 71% of urban and 58% of suburban voters supporting the party. Conversely, Republicans maintained a lead among voters aged 65 and older and continued to secure a majority of rural and small-town votes.

The data further highlighted a split regarding international policy, specifically the ongoing conflict in the Middle East. Among voters who characterized the joint U.S.-Israeli military actions against Iran as the correct decision, 91% supported Republican candidates. In contrast, 82% of those who opposed the intervention voted for Democrats, DW reported.

Special and Runoff Elections Fill Legislative Vacancies

What happens to the seats left vacant by members joining the executive branch?
Special elections are held to fill these vacancies. For instance, seats in Florida and Ohio were contested in 2026 after former senators Marco Rubio and JD Vance resigned to join the executive branch following the 2024 presidential election, as noted by The Guardian.

How do runoff elections affect the final seat counts?
In states like Georgia and Louisiana, candidates must receive at least 50% of the vote to win. If no candidate reaches that threshold, a runoff election between the top two finishers is required, which can delay the final determination of a seat’s winner.

How is a winner officially declared in a race?
The Associated Press determines the winner of a race when it calculates that the trailing candidate has no mathematical path to victory. This determination often occurs before every ballot is counted, based on projections and turnout data.

The 2026 midterm results changed congressional control similar to the 2006 election, when the Republican Party lost its majority in both chambers.
