Democratic Surge in Midterms Sets Stage for Congressional Clashes Over Iran and Trade

The United States House of Representatives and Senate have shifted to Democratic control following the midterm elections held on Tuesday, November 3, 2026. This result marks a significant defeat for President Donald Trump’s Republican Party, which had held majorities in both chambers during the first two years of the president's second term. The new Congress, set to convene in early January, will possess enhanced powers to scrutinize executive policies and obstruct legislation, although the president retains substantial authority to act without congressional approval.

One of the most immediate points of contention is the ongoing conflict between the United States, Israel, and Iran. President Trump acknowledged that the war influenced voter sentiment, though he maintained that the public recognized the importance of his actions. Frustration over inflation and rising costs for fuel and groceries drove many voters to back Democrats, who campaigned heavily on domestic affordability. The war began in February without a specific congressional authorization, a fact that may now complicate the president's military options.

Lawmakers in the new Democratic-led Congress can leverage their power to deny additional funding when the current government bill expires on December 11. However, experts note that cutting funds while troops are deployed could be politically risky, as it may be viewed as placing American lives at risk. James Boys, a research fellow at University College London, highlighted this challenge. Additionally, the War Powers Resolution, which limits military actions to 60 days without a declaration of war, is unlikely to constrain the president effectively because Democrats lack the two-thirds supermajority needed to override a potential veto.

Despite these limitations, Democrats may work with Republicans who are distancing themselves from the president to propose new legislation. Scott Lucas, a professor at the UCD Clinton Institute, pointed to Vice President JD Vance as a potential ally, noting his opposition to the war and his recent efforts to revive talks with Iran. Conversely, some analysts argue that Trump, no longer facing an election in his second term, may feel free to escalate his policies to establish a lasting legacy, particularly given his weakened domestic political standing.

Trade policy also faces scrutiny as Democrats seek to address the cost-of-living crisis exacerbated by tariffs. Last year, the administration imposed tariffs ranging from 10 percent to 50 percent on approximately 90 countries. Although the Supreme Court struck down the initial order in a 6-3 decision, the administration signed a new executive order raising tariffs to 15 percent under different statutes. These new tariffs are limited to 150 days unless extended by Congress, giving the new majority leverage to negotiate exceptions for exporters while deeper policy shifts await the 2028 election.

Legal disputes over tariff revenues remain ongoing, with questions about whether collected funds must be returned. In the technology sector, bipartisan support is expected for stricter restrictions on China's access to US technology. Key bills include the Remote Access Security Act and the Chip Security Act, which aim to extend export controls and verify the location of advanced artificial intelligence chips to prevent diversion to foreign adversaries.

The shift in power also means Democrats will chair all congressional committees, granting them the ability to launch investigations and issue subpoenas. This new authority could lead to examinations of the Trump family's business interests, the president's ties to Jeffrey Epstein, and Defense Secretary Pete Hegseth's management of the war in Iran. There is even discussion about a third impeachment attempt over the conflict. Furthermore, extensive investigations into immigration policies are planned, focusing on the collaboration between the Internal Revenue Service and the Department of Homeland Security in enforcing mass deportation policies.

The administration has defended its immigration crackdown, citing a statistic that about 70 percent of detainees have pending criminal charges. Critics, however, argue this figure is misleading given the legal presumption of innocence. A recent Fox News poll indicated that 53 percent of registered voters felt the crackdown had gone too far. With the new leadership in place, Democrats and moderate Republicans are expected to work with state and local communities to implement more responsible recovery policies.
