US midterms: 'Largely true' Iran war led to loss, Trump says

Democratic control of both chambers makes it harder for the Trump administration to pass laws, approve budgets, and advance major policies. The president still controls the executive branch, but Congress can refuse cooperation or require changes. The shift also gives Democrats stronger oversight powers.

For example, Congress controls federal spending. Democrats can use budget negotiations to restrict funding for administration priorities or condition money on specific actions. Committees can investigate officials and government programs. The Senate also has a role in confirming many presidential appointments. The article notes that Congress can influence troop levels in Europe and military planning.

Trump may still issue executive orders and direct executive agencies. German Chancellor Friedrich Merz expects him to continue bypassing Congress in that way. However, executive orders cannot replace every law or override Congress's constitutional control of money. Democrats could also consider impeachment, though Trump warned that doing so would damage their party.

US midterm elections are held halfway through a president's four-year term. They decide who represents voters in Congress for the next part of that presidency. Because the president is not on the ballot, midterms often become a national judgment on the administration's performance and policies.

Voters choose all 435 members of the House of Representatives every two years. They also elect roughly one-third of the Senate, whose members serve six-year terms on a staggered schedule. Many states hold gubernatorial and legislative elections at the same time. The article highlights Democratic victories in governor's races in Ohio and Georgia.

The 2026 results gave Democrats control of both the Senate and House. The contests also produced notable individual outcomes. Abdul El-Sayed became the first Muslim senator in US history, James Talarico won a Democratic Senate seat in Texas for the first time in decades, and Annie Andrews defeated Republican expectations in South Carolina.

Normally, voters contest 435 House seats in every midterm election. They also contest about 33 or 34 of the Senate's 100 seats, although the exact number can vary because of special elections. Many states also elect governors and state legislators. This creates a large national election without putting every federal office on the ballot.

The schedule reflects the Constitution's different term lengths. House members serve two-year terms, so every seat is up for election every two years. Senators serve six-year terms. Their elections are staggered into three groups, meaning roughly one-third of Senate seats face voters during each two-year election cycle. This prevents the entire Senate from changing at once.

The article reports that Democrats won control of both chambers in these midterms. That result is especially significant because Senate control normally changes through a smaller set of contests than House control. The new balance will affect budgets, oversight, appointments, military planning, and the administration's ability to pass legislation.

Vance and Trump linked the Iran war to Republican losses because they believed it changed how some voters cast their ballots. Vance said many people who supported Trump in the 2024 presidential election instead voted Democratic out of anger. He called the war the reason Republicans lost and specifically pointed to losing the Senate for six years.

Trump agreed that the war was “largely” responsible, but offered a narrower explanation. He said the conflict pushed gasoline prices up in the short term. Higher fuel costs can quickly affect household budgets and transportation expenses, making voters more dissatisfied. Trump nevertheless said he would make the same decision again because he believes Iran must not obtain a nuclear weapon.

The competing statements show the political cost of a major foreign-policy decision. Vance emphasized voter anger and the election result. Trump defended the strategic objective. The article reports that Democrats took both chambers, while Trump warned them against impeachment and said he was willing to work with them.

Gasoline prices can rise far from a conflict because oil is traded in interconnected global markets. A war can threaten production, pipelines, ports, or shipping routes. Even if a distant country loses no supply itself, traders may fear future shortages and bid up crude oil prices. Retail fuel prices can then follow.

The mechanism begins with uncertainty. If Iran or nearby routes appear less secure, buyers may compete for available oil and companies may pay more to insure or transport it. Refineries and fuel distributors can pass those higher costs through the supply chain. Currency movements, taxes, and local refining capacity also affect the final price paid by drivers.

In the article, Trump said the Iran war “drove the gasoline up a little bit short term.” He used that effect to support Vance's explanation for Republican losses, while still defending the military action. The reported price impact therefore became both an economic burden and a political liability for the administration.

An executive order is a written instruction from the president directing federal agencies or officials to take, stop, or organize certain actions. It uses authority already available to the executive branch. It does not pass through both chambers of Congress or receive congressional votes like a statute. Courts can also review whether an order is lawful.

A law passed by Congress follows the legislative process. The House and Senate approve the same text, and the president signs it or Congress overrides a veto. Laws can create programs, authorize spending, and impose requirements across the country. An executive order generally cannot create unlimited new authority or spend money that Congress has not provided.

The article says Friedrich Merz expects Trump to continue governing through executive orders after Democrats take control of Congress. That may let Trump act without congressional agreement in some areas. However, Democratic control could still restrict budgets, conduct oversight, and challenge actions in court or through legislation.

Separation of powers divides federal authority among Congress, the president, and the courts. The president leads the executive branch and serves as commander in chief. Congress writes laws, controls federal spending, oversees agencies, and sets many rules for military activity. This division prevents one branch from exercising unlimited control.

The key mechanism is the power of the purse. Congress must authorize and fund government programs, so it can approve, reduce, condition, or withhold money. The article says Congress can also influence troop levels in Europe and military planning. Congressional committees can investigate executive actions, while the Senate has confirmation responsibilities for many senior officials.

Foreign affairs involve shared powers. The president can direct diplomacy and military operations within legal authority, but Congress controls funding and can pass laws affecting policy. After Democrats won both chambers, they gained stronger tools to challenge administration choices. Merz expects Trump to keep using executive orders, but those orders cannot erase Congress's constitutional powers.
