US Senate Election Results 2026 Live Updates: Can Democrats flip the Senate as Trump faces crucial test?

The 2026 US midterm elections are shaping up as a crucial political test for President Donald Trump and the Republican Party, with control of Congress hanging in the balance. While Democrats are seen as having a stronger chance of making gains in the House of Representatives, their path to reclaiming the Senate remains considerably more challenging. Republicans currently hold a 53-47 advantage, including two independents who caucus with Democrats, and Democrats need to flip four Republican-held seats while defending their own to secure a majority.

Seven Senate races identified as toss-ups by the Cook Political Report could determine the outcome, with battleground contests unfolding in states such as Michigan, Alaska, Texas, Iowa, Ohio, Kansas and Maine. The races have also exposed divisions within the Democratic Party, particularly in Michigan, where former congresswoman Haley Stevens’ endorsement of Republican Mike Rogers against Democrat Abdul El-Sayed triggered criticism from party members.

Texas has emerged as a major financial battleground, with spending on Senate race advertisements reaching a record $573 million. In Alaska, a legal challenge seeking to block certification of the results if Republican Dan Sullivan narrowly loses was dismissed, adding another dimension to the contest against Democrat Mary Peltola. Meanwhile, veteran Republican senator Susan Collins faces a tough re-election fight in Maine.

The cost of living, Trump’s political standing and debates over immigration and foreign policy are influencing campaigns across these states. With 55 million votes already cast early, the results could determine not only the balance of power in Congress but also Trump’s ability to advance his legislative agenda, influence investigations and secure judicial nominations during the remainder of his presidency.
