Three issues defining the 2026 US midterm elections

US midterm elections occur halfway through a president's four-year term. Voters choose members of Congress rather than the president. These elections matter because Congress writes laws, controls federal spending, and can investigate the administration. The results can therefore limit or strengthen a president's agenda.

Voters choose representatives for the House and senators for the Senate. House elections cover all 435 seats, while only some Senate seats are contested in any one midterm. The article focuses on whether Republicans retain their narrow majorities or Democrats gain control of both chambers.

The November 3 elections are unusually nationalized around Donald Trump, affordability, and immigration. Competitive races will decide the balance. A change in control could determine whether Democrats challenge Trump's administration or Republicans continue advancing its priorities.

Republicans currently control both the House of Representatives and the Senate, but their majorities are narrow. That means a relatively small number of competitive races could determine which party controls Congress after the election. The balance is especially important because Congress can shape legislation and challenge presidential actions.

The article states that Democrats need a net gain of four seats to take control of each chamber. A net gain means Democratic victories must outweigh any seats the party loses elsewhere. The result will depend on a limited group of closely contested races rather than every district receiving equal attention.

Trump is making the contest more national, while affordability and immigration are central voter concerns. If Democrats reach the four-seat gain, they could challenge the administration more directly. If Republicans hold their seats, they would retain control of Congress.

A president's popularity can influence midterms even when the president is not running. Voters may treat congressional races as a judgment on the administration. Strong approval can help the president's party, while poor approval can motivate opponents and independents to vote against it.

Trump is campaigning aggressively, with rallies planned in Florida, Iowa, Michigan, and Texas. He has urged voters to act as if he were on the ballot. The Reuters/Ipsos poll cited in the article puts his approval rating at 31%, its lowest recorded level. That message may increase turnout among his base.

It could also produce the opposite effect. Democrats and independents may become more determined to oppose Republican candidates associated with Trump. The final impact will depend on which side turns frustration into votes in the relatively small number of competitive races.

Affordability matters because voters feel price changes in essential household bills. When healthcare, fuel, groceries, and housing become more expensive, families have less money available for other needs. Those daily pressures can outweigh more distant policy debates and shape judgments about whether lawmakers are delivering on promises.

The Reuters/Ipsos poll found that half of registered voters called the cost of living the most important factor in their vote. Gas averaged $4.28, up $1.20 from a year earlier, while diesel averaged $6.32, up $2.70. Grocery costs rose 1.8%, and home prices increased 2.1% over the past year.

Both parties face accountability over these pressures. Democrats accuse Trump of breaking promises to lower costs and propose an affordability agenda. Republicans point to their tax-cut extension, which reduced spending for Medicaid and other health programs, while Democrats emphasize healthcare subsidies and household costs.

The border situation has changed sharply under the current administration. Preliminary Department of Homeland Security data show a 95% drop in migrants apprehended at the southwest border compared with Joe Biden's administration. The agency also reported no Border Patrol releases during the fiscal year, described as a first.

Yet lower apprehensions have not ended the political conflict. Fatal encounters with federal immigration agents occurred in Maine, Minnesota, and Texas. The deaths of two US citizens in Minnesota pushed some Democratic candidates left, including calls to impeach Kristi Noem or abolish Immigration and Customs Enforcement.

Funding and enforcement remain major disputes. Republicans passed a $70 billion bill for ICE and Border Patrol after a stalemate, while Democrats condemned the policy and Republicans accused them of supporting open borders. A raid involving Representative Ilhan Omar intensified Democratic criticism and raised questions about citizenship and deportation.

Controlling both chambers gives a party the strongest congressional position available short of holding the presidency. It can set legislative priorities, decide which bills receive consideration, and use committees to examine executive actions. Congress also controls federal spending, making budget decisions a major source of influence.

Democrats say control would let them pursue an affordability agenda and hold Trump's administration accountable for alleged corruption. Their priorities could include reducing household costs and challenging policies they oppose. Republicans, if they retain control, could continue implementing their legislative program, including their tax-cut extension and immigration funding priorities.

The president would still lead the administration, so congressional control would not automatically end executive policies. However, the balance could change negotiations, oversight, funding, and political pressure. The election's practical consequence is whether Congress reinforces Trump's direction or becomes a stronger obstacle to it.

The United States divides federal power among the presidency and Congress. The president leads the executive branch and directs the administration. Congress consists of the House of Representatives and Senate, which make laws, approve spending, and oversee government activity. This separation prevents one institution from holding all national power.

The two chambers have different memberships and election cycles, but both must generally support legislation. A president may pursue an agenda, while Congress can support, revise, delay, or investigate it through its lawmaking and funding powers. The article's disputes over Medicaid, health subsidies, immigration funding, and accountability show how those powers affect policy.

Midterm elections matter because they can change Congress without changing the president. If the president's party keeps both chambers, it faces fewer congressional obstacles. If the opposing party gains control, it can scrutinize the administration and challenge its priorities more forcefully.
