U.S. midterm polls open on a consequential vote for Americans and Trump

The brief

U.S. midterm elections take place halfway through a president’s four-year term. Voters choose members of Congress, not the president, and the results can limit or strengthen the administration’s lawmaking power. In this election, all 435 House seats and 35 Senate seats are on the ballot. For example, Democrats hoped to win enough Senate contests to reach 51 seats, giving them control of that chamber and greater power over legislation, confirmations, and oversight. Republicans held 219 House seats, only a one-seat majority, while Democrats led the congressional voting preference, 47% to 36%, in an Ipsos poll. A Democratic takeover of one or both chambers could hobble Trump’s legislative agenda, although he would still retain executive-order powers as president. The final results were expected early Wednesday after Alaska’s polls closed at 1 a.m. Eastern.

What are U.S. midterm elections, and what offices are being voted on in this election?

U.S. midterm elections take place halfway through a president’s four-year term. Voters choose members of Congress, not the president, and the results can limit or strengthen the administration’s lawmaking power.

In this election, all 435 House seats and 35 Senate seats are on the ballot. For example, Democrats hoped to win enough Senate contests to reach 51 seats, giving them control of that chamber and greater power over legislation, confirmations, and oversight.

Republicans held 219 House seats, only a one-seat majority, while Democrats led the congressional voting preference, 47% to 36%, in an Ipsos poll. A Democratic takeover of one or both chambers could hobble Trump’s legislative agenda, although he would still retain executive-order powers as president. The final results were expected early Wednesday after Alaska’s polls closed at 1 a.m. Eastern.

02

How many seats in Congress are up for election—35 in the Senate and how many in the House?

Congress has 470 seats up for election in this cycle: 35 in the Senate and all 435 in the House. These elections matter because control of either chamber shapes whether the president can advance legislation. A change in control could weaken Trump’s legislative agenda for the next two years.

For example, Republicans held 219 House seats going into Tuesday. That was a one-seat majority, making all 435 House races especially important. Democrats needed 51 Senate seats, meaning they had to retain 47 and win four more.

The source says 47 percent planned to vote Democratic in their district, compared with 36 percent Republican. Eleven percent remained undecided as of October 26. Even if Democrats won both chambers, Trump would retain executive power, including the ability to issue executive orders.

03

Why could Democrats’ winning control of one or both chambers of Congress obstruct Trump’s legislative agenda?

Congress must pass laws, approve spending, and shape national policy, so party control matters. If Democrats won either chamber, they could refuse or rewrite proposals supporting Trump’s legislative agenda. Controlling both chambers would make that resistance stronger, though Trump could still use executive orders.

For example, Democrats needed 51 Senate seats, while Republicans held only a one-seat House majority. A Democratic Senate could block bills or require major compromises, while a Democratic House could stop legislation before it advanced. Together, both chambers could deny Trump the congressional approval needed for much of his program.

The risk was significant because midterms often punish the White House party. Polls showed 47 percent planned to vote Democratic, versus 36 percent Republican. That narrow margin threatened to stall Trump’s agenda for two years, but it would not erase presidential power.

04

What is the difference between the Senate and the House of Representatives, and why do both matter for passing laws?

The Senate gives each state equal representation: two senators, serving six-year terms. The House reflects population, with 435 representatives elected every two years. Both chambers must approve the same bill before the president can sign it, so control of either chamber can block legislation.

In these elections, 35 Senate seats and all 435 House seats are contested. Democrats needed 51 Senate seats, including holding their current 47, to control that chamber. Republicans held 219 House seats, only a one-seat majority, making House control especially vulnerable.

As of Oct. 26, 47 percent of voters planned to vote Democrat for Congress, compared with 36 percent Republican. A Democratic win in either chamber could obstruct Trump’s legislative agenda, although he could still act through executive orders. Thus, elections determine not only who represents voters, but which proposals can become law.

05

Why do midterm elections often punish the party that controls the White House?

Midterm elections often punish the president’s party because voters judge the administration’s performance. They can express frustration without choosing a new president, while opposition voters may be especially motivated to participate.

A clear example came in 2018, when Democrats gained 41 House seats during Donald Trump’s presidency. Economic concerns, opposition to Trump, and strong Democratic turnout helped shift control of the House. That change limited Trump’s ability to pass legislation without Democratic support.

The article describes similar risks for Republicans, who held 219 House seats before voting. Ipsos found that 47 percent planned to vote Democrat, compared with 36 percent Republican. If voters repeat this pattern, Democrats could control one or both chambers. However, Trump would still retain executive powers, including issuing executive orders, even if Republicans lost Congress.

06

What powers would Trump still have if Republicans lost control of both chambers of Congress?

Even if Democrats won both chambers, Trump would remain president and retain significant executive power. That includes issuing executive orders, which direct federal agencies and can shape policy without a new vote in Congress. However, orders cannot replace laws passed by Congress and may face court challenges.

For example, in 2017, Trump signed an order directing agencies to review ways to reduce Affordable Care Act burdens. That shows the mechanism: the president can instruct the executive branch, even when lawmakers resist. But Congress still controls legislation and federal spending, limiting how far those directives can go.

The article says Trump would keep this authority even after losing both chambers. Democrats hoped a “blue wave” would hobble his legislative agenda for two years. Republicans entered the election with 219 House seats, while Democrats needed 51 Senate seats. Divided government could slow new laws while leaving Trump able to act administratively.

07

How do elections, congressional majorities, and the separation of powers determine what the U.S. government can actually do?

The U.S. divides power between the president and Congress so neither side controls everything. Elections choose lawmakers, while congressional majorities control votes on legislation, investigations, and government funding. This makes election results important even without changing the presidency.

For example, Republicans held 219 House seats, only a one-seat majority, going into Tuesday. If Democrats won enough seats, they could block or reshape Trump’s legislative plans because bills need congressional approval. Yet Trump could still act through executive orders, even after losing both chambers.

That tension shaped this election: 47 percent intended to vote Democratic locally, versus 36 percent Republican, with 11 percent undecided. Democrats needed 51 Senate seats, requiring them to hold 47 and persuade Trump voters to switch. A Democratic takeover could hinder Trump’s agenda, but it would not remove his presidential powers.
