The Democratic Party secured control of both the House of Representatives and the Senate in the United States midterm elections held on November 3, 2026, dealing a significant political blow to President Donald Trump. As reported by detikNews, the results mark a major shift in Washington’s power dynamics, ending Republican control of Congress and signaling the start of a divided government when the new legislative session begins in January 2027. This outcome has created a serious political paradox, as the loss of the ruling party’s majority typically encourages a president to re-evaluate unpopular policies, yet in the context of the U.S.-Iran war, it may increase the political incentive for the administration to escalate military operations to maintain leadership credibility.
Legislative Shifts in the House and Senate
The scale of the Democratic victory exceeded initial expectations, according to projections from the Associated Press. In the House of Representatives, Democrats are on track to hold 222 seats compared to 138 for the Republicans, with 75 races still undecided. While some reports indicated a potential for 245 Democratic seats, current counts confirm 225 legislators elected to the House compared to 137 for the Republicans. In the Senate, Democrats and their affiliated independents are projected to control at least 54 seats, while Republicans hold 44, with two contests remaining. Across the country, Republican support dropped in roughly 99% of the 2,100 counties where counting is partially complete, with an average decline of 9 percentage points compared to the 2024 presidential election. In 64 majority-Latino counties, that decline reached 14 percentage points.
In Kansas, Adam Hamilton became the first Democratic senator elected since 1932.
Congress Demands Limits on Executive Power
The midterm results reflect widespread voter dissatisfaction with the current administration, particularly regarding the ongoing conflict between the United States and Iran. Approximately half of the electorate viewed the vote as a direct rebuke of President Trump, with 70% calling for Congress to increase checks and balances on executive power. Reuters noted that nearly 9 out of 10 voters cited the cost of living as a critical factor in their decision.
The geopolitical and economic ripple effects were immediate. CNBC Indonesia reported that global commodity markets reacted sharply to the election results. Prices for oil, coal, and crude palm oil (CPO) faced downward pressure as markets anticipated a potential cooling of tensions between Washington and Tehran. Conversely, assets like gold, silver, and copper saw increased momentum. Nickel prices, however, saw a less direct impact, remaining far below their May 2026 peak of nearly US$19,500 per ton.
Military Costs and Strategic Dilemmas
The war with Iran has become a mounting fiscal and political burden. By October 16, 2026, the cost of the conflict had reached US$ 47,1 miliar, covering operational expenses, ammunition, and lost military equipment, as detailed by detikNews. The Pentagon reported 21 U.S. military deaths and 865 injuries, figures that complicate the administration’s initial framing of the operation as a brief military engagement. President Trump and Vice President JD Vance have both acknowledged that the eight-month war and rising gasoline prices negatively impacted the Republican Party’s performance.

On November 2, 2026, the U.S. launched a limited strike on Qeshm Island near the Strait of Hormuz.
Future Oversight and Congressional Authority
Starting in January 2027, the divided government formed after the midterm elections will give Congress the authority to conduct investigations into various government matters, including policies related to the Iran conflict. In Israel, analysts are already identifying three major challenges the country must face following the Republican defeat, according to an analysis published in The Jerusalem Post on November 4, 2026.
