US midterm elections approach: Control of Congress to be decided by November 3 vote

BlockBeats news, September 25 — The U.S. 2026 midterm elections will be held on November 3, with all 435 House seats and 35 Senate seats up for re-election. Republicans currently control both chambers of Congress, with a narrow majority in the House. According to the latest assessment by the Cook Political Report, 21 House seats are rated as "toss-ups," while 7 Senate seats are in similarly competitive races.

The economy and cost of living, the Iran war, and oil prices have become key issues in this election cycle. The latest CNN/SSRS poll shows that only 27% of respondents approve of Trump's handling of the economy, and Democratic candidates lead Republicans by 8 percentage points in the national congressional "generic ballot." In addition, a Reuters/Ipsos poll in September showed Trump's overall approval rating at 32%, a new low in his political career, with inflation and the ongoing Iran war cited as among the important factors behind respondents' dissatisfaction with his performance.

If Democrats win enough seats in the elections to control the House or the Senate, it would change the partisan composition of Congress and affect the Trump administration's subsequent legislative and policy agenda.
