US midterm elections 2026: Three possible outcomes and what they mean for Trump

A Democratic victory, a divided Congress or a Republican comeback: three possible outcomes could emerge from the 2026 US midterm elections, which are being closely watched as a test of President Donald Trump's leadership.

Although Democrats have gained ground in opinion polls, the final outcome will depend on a series of closely contested races across the country. Track live updates US President Donald Trump after delivering remarks ahead of the midterm elections at the Lincoln Memorial Reflecting Pool.

Midterm elections are held halfway through a president's four-year term. Historically, the president's party has often lost seats in these contests, as voters use the elections to express their views on the government's performance.

That said, winning the House and taking control of the Senate are two different challenges. Democrats could make significant gains in one chamber without securing a majority in the other.

In the first scenario, Democrats secure control of both chambers, giving them greater power to challenge Trump's policies and decisions. Democrats need to gain four seats in the House and four in the Senate to overturn the Republicans' current majorities, according to Reuters.

Republicans currently holds 218-214 advantage in the House and 53-47 lead in the Senate. A strong Democratic performance could help the party win seats in states that have traditionally supported Republicans. Key Senate contests in Texas, Ohio, Iowa and Alaska could play an important role in deciding control of the chamber.

They could also use their majorities to challenge government policies on issues such as immigration, tariffs, healthcare and the war with Iran. A Democratic majority would not mean that Trump loses his powers as president.

He would retain the ability to veto legislation and exercise executive powers, although passing new laws could become more difficult. A Democratic takeover of both chambers could also give the party greater influence over government funding, judicial appointments and negotiations on major economic issues, as per AP.

The second possibility is a divided Congress, with Democrats taking control of the House while Republicans retain their majority in the Senate.

Republicans would continue to control the Senate, though, limiting the Democrats' ability to get their proposals approved. This scenario would also mean that Trump would have to deal with opposition-controlled committees in the House while retaining Republican support in the Senate.

According to a Reuters analysis of possible election outcomes, a Democratic-controlled House could investigate the administration's decisions, including its immigration policies and handling of the war with Iran. It could also pass bills on healthcare, housing and other domestic issues, although Republican opposition in the Senate and Trump's veto power could prevent many of them from becoming law.

The third scenario involves Republicans holding on to both the House and the Senate, despite the Democratic gains suggested by several opinion polls.
