Democrats mount major Senate upsets and flip House seats in US midterms

Democrats surged ahead in pivotal battlegrounds across the United States in Tuesday’s midterm elections, capitalizing on widespread economic frustration and persistent public disapproval of President Donald Trump to score major upsets in the Senate and flip competitive congressional districts.

Which key Senate seats did Democrats flip in early midterm results?

According to CBS News, Democrats recorded high-profile victories in the upper chamber, headlined by a major upset in South Carolina where Democrat Annie Andrews defeated incumbent Republican Senator Darline Graham to flip the seat. In North Carolina, former Democratic Governor Roy Cooper captured another Republican-held Senate seat, defeating Michael Whatley in a closely watched contest.

According to CNN, Democrats also defended key battlegrounds, with incumbent Senator Jon Ossoff turning back a challenge from Republican Representative Mike Collins in Georgia, and Representative Chris Pappas securing victory in New Hampshire to retain the seat following the retirement of Senator Jeanne Shaheen. Meanwhile, in Florida, Republican Senator Ashley Moody won her special election to serve the remainder of the unexpired term vacated by Secretary of State Marco Rubio.

How did Democrats perform in battleground House districts?

In the fight for the House of Representatives, Democrats made early strides toward erasing the narrow Republican majority. Democratic candidate Jamie Ager flipped North Carolina’s 11th Congressional District, securing the party’s first victory in the western North Carolina seat since 2010.

Democrats also resisted redistricting headwinds across the Sun Belt, defending key seats in Florida where Representatives Kathy Castor and Jared Moskowitz retained the 14th and 25th Congressional Districts, respectively. The early pickups provided Democrats critical momentum toward the 218-seat threshold required to secure the speaker’s gavel.

What did national exit polls reveal about voter anger and Trump's economic record?

The Democratic momentum was underpinned by widespread voter backlash captured in preliminary national returns from the CNN Voter Poll. Roughly three-quarters of voters nationwide reported feeling dissatisfied or angry with the country’s direction, with approximately 4 in 10 explicitly describing themselves as angry. Dissatisfaction was primarily fueled by negative appraisals of the president and compounding cost-of-living strains.

About 6 in 10 voters nationally expressed disapproval of Trump’s job performance, with roughly half stating they disapproved strongly.

The survey exposed visible cracks within the president’s 2024 coalition, revealing that nearly one-fifth of voters who supported Trump two years ago now disapprove of his administration.

Economic anxiety heavily influenced decisions at the ballot box. Around three-quarters of respondents described national economic conditions as poor, and nearly 9 in 10 cited the cost of living as a "crucial" or major factor in their voting choice.

About two-thirds of voters stated that Trump’s policies had worsened economic conditions, directly tying elevated living costs to White House actions rather than external global disruptions.

The exit polling also revealed that the administration's appeal to base voters to treat the midterm election as a direct referendum on the executive branch failed to win over independents.

Fewer than 20 percent of voters stated they cast their congressional ballots in support of Trump, with the majority voting either in direct opposition to the president or viewing his administration as non-essential to their local House and Senate selections.

According to The Associated Press (AP), while vote tabulation continues across highly contested West Coast and southwestern districts, strong turnout among independent and suburban voters continues to fuel Democratic leads as election offices process millions of outstanding mail-in and provisional ballots.
