WASHINGTON, UNITED STATES: Millions of Americans went to the polls on Tuesday, 3 November 2026, in an election that did not choose a new President but could significantly change how the country is governed.
The results have produced a major shift in Washington.
According to the Associated Press, the Democratic Party has secured control of both the US House of Representatives and the Senate, taking congressional power away from the Republican Party.
Yet President Donald Trump, a Republican, remains in the White House.
For many people outside the United States, particularly those familiar with parliamentary democracies such as New Zealand, India and Australia, this may seem confusing.
How can one party control the presidency while another controls Congress? Why does America vote every two years? And does this result mean Trump has lost his power?
The answers lie in how the American Constitution separates political authority.
The United States has three branches of federal government.
The President and executive branch: The President leads the executive branch, oversees federal government operations, directs foreign policy and serves as commander-in-chief of the armed forces.
Congress: Congress is the legislative branch. It passes federal laws, approves government spending and exercises oversight of the executive branch.
The judiciary: Federal courts, including the Supreme Court, interpret laws and decide constitutional disputes.
Unlike New Zealand or India, the American President does not need to maintain the confidence of a parliamentary majority to remain in office.
This separation is one of the most important features of the US political system.
The American President serves a four-year term, but Congress operates on a different electoral timetable.
Congress has two chambers: the House of Representatives and the Senate.
| Institution | Total seats | Term | Election cycle |
|---|---|---|---|
| President | 1 | 4 years | Every 4 years |
| House of Representatives | 435 | 2 years | All seats every 2 years |
| Senate | 100 | 6 years | Approximately one-third every 2 years |
Every two years, American voters elect all 435 voting members of the House of Representatives.
At the same time, approximately one-third of the Senate's 100 seats are contested.
This means the composition of Congress can change halfway through a President's four-year term.
The elections held between presidential elections are called midterm elections.
For example:
2024: Presidential election and congressional elections.
2026: Midterm congressional elections, without a presidential election.
2028: Next scheduled presidential election, alongside congressional elections.
2030: Another midterm election.
The President's four-year term continues regardless of whether the President's party wins or loses the midterms.
The 2026 midterms took place on 3 November.
Before the election, Republicans controlled both chambers of Congress.
The Associated Press subsequently declared Democratic control of the Senate on election night and Democratic control of the House early on 4 November.
That means Democrats have secured the congressional majorities needed to take control of both chambers when the newly elected Congress begins its term.
Some individual contests may still require final counting or certification, but the overall congressional outcome has been called.
The new Congress is scheduled to begin on 3 January 2027.
Until then, the outgoing Congress continues to exercise its existing legislative authority.
No. Donald Trump remains President of the United States.
He was elected in 2024 for a four-year term beginning on 20 January 2025.
That term is scheduled to continue until 20 January 2029.
The 2026 midterms were not a presidential election.
They did not directly determine whether Trump could remain in office.
However, they have changed the political environment in which he will govern during the remaining two years of his presidency.
This is where the results become particularly important.
A President can continue exercising executive powers even when the opposition controls Congress.
But passing major legislation can become considerably more difficult.
For example, imagine President Trump proposes a new tax law, a major immigration reform or a substantial change in federal spending.
His administration can develop and promote those policies.
However, legislation generally requires approval from both the House and Senate before it can be presented to the President.
With Democrats controlling both chambers, Republican legislative proposals may face stronger resistance, substantial amendments or outright rejection.
The same principle works in reverse.
Democrats may pass legislation that Trump opposes, but the President can veto bills presented to him.
Congress can override a presidential veto only with a two-thirds vote in both chambers.
This creates a system in which neither the President nor Congress can independently make every major policy decision.
Yes.
Congress has oversight powers that allow lawmakers to investigate federal government activities, question officials, request documents and examine how public money is being spent.
Control of congressional committees is particularly important.
When Democrats assume leadership of the new Congress, they will gain greater authority over committee agendas and investigations.
This could result in more scrutiny of the Trump administration's decisions, spending, appointments and policies.
However, investigations do not automatically establish wrongdoing.
Any findings must be assessed according to the evidence and applicable law.
The US Constitution provides an impeachment process.
The House of Representatives has the power to impeach a President by a simple majority vote.
The Senate then conducts a trial.
Removing a President following impeachment requires a two-thirds majority of senators present.
Therefore, even when the opposition controls both chambers, impeachment does not automatically mean removal from office.
It is also important to understand that impeachment is a constitutional process, not a replacement for an ordinary presidential election.
Although both chambers form Congress, their structures and responsibilities differ.
The House of Representatives has 435 voting members, with representation distributed among states according to population.
Its members face voters every two years.
The Senate has 100 members, with every state receiving two senators regardless of population.
Senators serve six-year terms, but those terms are staggered.
This means only about one-third of the Senate is normally elected at each two-year congressional election.
The Senate also has special responsibilities, including confirming many presidential appointments and approving treaties under constitutional procedures.
The House has the sole power to initiate impeachment, while the Senate conducts impeachment trials.
Both chambers play essential roles in federal lawmaking.
The election took place against a backdrop of debate over living costs, economic conditions, government policy and the direction of the Trump administration.
Associated Press reporting identified concerns over inflation, household expenses, government accountability and the Iran war among issues influencing the political environment.
However, national election results should not be reduced to one explanation.
Voters in different states and congressional districts can have different priorities.
Some races were influenced by local candidates, district boundaries and state-specific issues.
The broader result shows a change in congressional representation, but it does not mean every American voter supported the same policies or voted for the same reasons.
The period from January 2027 to January 2029 could involve more negotiation between the White House and Congress.
Three areas will be particularly important.
Government spending and budgets: Congress plays a central role in approving federal spending. Disagreements could complicate budget negotiations and government funding.
Domestic legislation: Major changes involving taxation, healthcare, immigration and other federal laws may require compromises between Democrats and Republicans.
Congressional oversight: Democratic control of committees could lead to more hearings, investigations and examination of executive decisions.
However, Congress does not control every presidential action.
The President retains constitutional and statutory executive powers, subject to legal limits and judicial review.
The actual impact will depend on the legislation proposed, the positions taken by lawmakers and the willingness of both parties to negotiate.
This is perhaps the easiest way for international readers to understand the American system.
In New Zealand, the Prime Minister leads a government that must retain the confidence of the House of Representatives.
In India, the Prime Minister similarly heads a government that depends on the confidence of the Lok Sabha.
If a government loses the necessary parliamentary support, its ability to remain in office can be affected.
The United States operates differently.
The President is elected separately from Congress and serves a fixed constitutional term.
Even if the President's party loses control of Congress, the President does not automatically resign or face a new presidential election.
This arrangement is commonly described as divided government.
It has occurred repeatedly throughout American history under presidents from both major political parties.
American political developments can have consequences beyond the United States.
The US is a major global economy and an important trading and diplomatic partner for countries including New Zealand and India.
Changes in congressional control may influence debates involving trade policy, international funding, economic regulation and foreign relations.
For New Zealand businesses, exporters and investors, the practical question is whether political disagreements lead to changes in American law or policy.
For Indian and other migrant communities with family, business or professional connections to the United States, developments involving immigration legislation and federal policy may also be relevant.
However, a change in congressional control does not automatically change visa rules, tariffs or other existing policies.
Those changes must be examined individually.
The newly elected Congress will begin its term on 3 January 2027.
Democrats will then have the opportunity to organise their congressional leadership and committee structures.
President Trump will continue in office, with the next presidential election scheduled for November 2028.
The central political question is how the Democratic-controlled Congress and Republican White House will work together, or disagree, over legislation, government spending and oversight.
The constitutional system gives both sides significant powers, but neither side unlimited authority.
The 2026 midterm elections demonstrate a distinctive feature of American democracy.
Voters do not have to wait four years to change the political balance in Washington.
Every two years, they can elect a new House of Representatives and part of the Senate, potentially changing the party controlling Congress without changing the President.
That is exactly what happened in 2026.
Donald Trump remains President. Democrats have won control of Congress. And the next phase of American politics will involve two different political parties exercising power in separate branches of government.
The simplest way to understand the result is this: Americans did not elect a new President in November 2026. They elected a new Congress, and that decision changes how the existing President can govern.
