The Democratic Party has secured control of the United States Senate following a series of victories in the November 3 midterm elections, giving it a majority in both chambers of Congress.
NBC News projected that Democrats had won 54 Senate seats, compared with 44 for Republicans, after defeating several Republican candidates in states that had supported President Donald Trump in the 2024 presidential election.
The outcome represents a major change in the political balance in Washington and is expected to affect the final two years of Trump’s presidency.
Democrats recorded victories in seven Republican-held Senate seats, with major gains in Texas, Iowa, Kansas, Ohio, Maine, North Carolina and South Carolina.
In Texas, Democrat James Talarico defeated Republican Ken Paxton, while Josh Turek secured victory over Ashley Hinson in Iowa.
Kansas also recorded a Democratic breakthrough, with Adam Hamilton winning the Senate seat against Republican Roger Marshall. In Ohio, Democrat Sherrod Brown defeated incumbent Jon Husted.
In Maine, Troy Jackson unseated Republican Senator Susan Collins, while Roy Cooper won in North Carolina against Republican Michael Whatley.
South Carolina also went to the Democrats, with Annie Andrews defeating Republican Senator Lindsey Graham.
The party equally retained important seats, including Georgia, where incumbent Jon Ossoff defeated Republican challenger Mike Collins. In New Hampshire, Chris Pappas won the contest against former senator John Sununu.
However, the final composition of the Senate remained uncertain because the races in Alaska and Mississippi had not been called as of November 5.
In Mississippi, Democrat Scott Colom held a narrow lead over Republican incumbent Cindy Hyde-Smith, with thousands of provisional ballots still awaiting resolution. The state was expected to address the outstanding ballots by November 10.
Alaska also remained closely contested between Republican incumbent Dan Sullivan and Democrat Mary Peltola. The result could be affected by the state’s ranked-choice voting system if no candidate receives more than half of the first-choice votes.
The Democratic gains were not limited to the Senate. The party also secured control of the House of Representatives, giving it command of both chambers of Congress for the first time during Trump’s current presidency. NBC Chicago+2
The change in congressional control is expected to have significant implications for the administration. Democrats will have greater influence over the legislative agenda, congressional investigations and the confirmation of presidential nominees.
The election outcome has also been linked to widespread voter dissatisfaction with economic conditions, the cost of living and the direction of the country. A survey of more than 90,000 voters found that economic concerns and disapproval of Trump’s performance were major factors behind the Democratic gains. The Washington Post+1
With the new majority expected to take effect when the next Congress convenes in January, Democratic leaders have indicated that affordability and accountability will feature prominently in their agenda.
Although the outstanding contests in Alaska and Mississippi could still alter the final seat count, the Democratic Party has already secured enough victories to take control of the Senate.
