Midterms — You don’t have to be a political obsessive to know what to watch for on Nov. 3. (Getty Images)

Politics can be a lot. Keeping track of what’s going on can be confusing, frustrating, unsettling and, often, pretty boring. It’s no surprise that a large share of Americans feel compelled to step back from following politics or give up on it entirely.

As understandable as it is to give yourself some distance, that does mean it can be hard to get caught up when something important — like next week’s big midterm election — comes up. That’s exactly what this story is meant to help with.

There’s no need to bombard you with every single twist and turn in U.S. politics since President Trump was elected to a second term two years ago. Instead, consider this a zoomed-out, stripped-down cheat sheet of the things you really do need to know to understand what’s happening, why it matters and how you can take part yourself on Nov. 3.

The 2026 midterm election will be held Nov. 3

What’s happening?

The midterms happen in even years when there’s not a presidential election (they’re called that because they happen in the middle of a president’s term).

This year, all 435 seats in the House of Representatives, as well as 35 of 100 Senate seats and the governorship of 36 states, are on the ballot. That means every eligible voter in all 50 states has the chance to, at minimum, vote for their congressional representative. Voters in 26 states can cast their ballots for all three.

What’s at stake?

Presidential races are obviously the headliner when it comes to U.S. elections, but midterms are very important too. Republicans have had a “trifecta” — control of both chambers of Congress and the presidency — since January 2025. Unified control in Washington has allowed Republicans to turn Trump’s favored legislation — like his One Big Beautiful Bill Act, a tax and spending plan — into law. It has also helped Trump get allies like Defense Secretary Pete Hegseth and Health Secretary Robert F. Kennedy Jr. confirmed to his Cabinet and made it harder for Democrats to rein in Trump’s military actions in Iran..

Flipping just one chamber of Congress would give Democrats an effective veto on any legislation Republicans wanted to pass over the final two years of Trump’s presidency. It would also provide them with leverage during negotiations over must-pass legislation, like government funding bills or the defense budget. House Democrats are already signaling plans to launch a wide range of investigations into the president and his allies, and even potentially pursue impeachment proceedings, if they gain control of the chamber.

Taking over both the House and Senate would give Democrats even more power to block Trump’s agenda. With both chambers under their control, they could pass their own legislation, potentially forcing the president to veto popular bills. They would also have the ability to block Trump’s nominees for Cabinet positions from being confirmed and prevent him from filling any vacancies that arise on the Supreme Court.

The midterms will also have a major impact on individual states, including a number of key swing states where the governorship is up for grabs.

What do the polls say?

For months, polls have generally suggested that we could see a “blue wave” of Democratic victories across the country. But whether that happens, and how big the wave might be, remains to be seen.

Forecasters generally expect Democrats to take back the House, potentially with a significant majority. There’s much more uncertainty about the Senate. Right now, the polls are showing Democrats doing much better than they historically have in some of the traditionally Republican states, like Texas, Kansas and South Carolina. At the same time, races in some swing states also appear to be quite close. That means that any of the dozen or so competitive Senate contests could be the one that decides control of the chamber.

The polls could be wrong, of course. They have underestimated Republicans to varying degrees in three separate elections during the Trump era. Even a polling error of a few percentage points could mean Republicans wouldn’t have to worry about losing the Senate, though the House could still flip. Those recent polling errors were all presidential years, however. The polls have been more accurate over the past two midterm cycles.

Midterms also tend to go poorly for the party that controls the presidency, especially when the president’s approval rating is low — as Trump’s is right now.

What are the biggest issues?

Trump isn’t on the ballot this year, but he looms large over the most important issues of the midterms: cost of living and the economy, which are at least partially tied to the president’s tariffs and the war in Iran. A recent survey found that both were at the top of the list when voters were asked which issues will influence their votes the most.

Candidates from both parties have focused heavily on affordability in their midterm messages, with Democrats blaming Trump and the GOP for rising costs, and some Republicans breaking from the president by calling for an end to the war or the reversal of tariffs.

A recent poll showed that most voters want Congress to exert more influence over Trump’s policies, either to roll them back or to act as a check on his actions.

Other polls have shown that voters are highly concerned about corruption in government and protecting America’s democracy. Issues like health care, immigration, education and crime are also weighing heavily on voters, as they do in most elections.

Many Republicans have made the issue of transgender rights, specifically trans athletes’ participation in girls’ and women’s sports, a significant part of their midterm message. Though polls show that Americans share concerns about trans athletes playing in these sports, other surveys suggest the issue ranks low on the list of factors that will influence how they vote.

One topic that’s emerged as a major election issue for many voters this year is data centers. These facilities, which house the servers and other infrastructure that allow the internet to function, have become a point of contention for voters who oppose having them built in their communities. The American public’s opposition to data center construction has grown remarkably quickly, and candidates from both parties are adjusting their positions on the fly to try to keep up with voters’ opinions.

What to watch in the House

About 80% of the 435 total House races on the ballot are not considered to be competitive. That leaves about 80 or so districts that could decide which party wins control of the House. The majority of those competitive seats are currently held by Republicans, which means they face a steep challenge as they try to hold on to their narrow House majority. In fact, many forecasters believe Democrats will take over the chamber.

“Republicans’ path to keeping control of the House has all but evaporated,” Erin Covey, an analyst with the nonpartisan Cook Political Report, wrote last week.

The real question about the House seems to be: If Democrats win control of the chamber, how many seats will they win?

What to watch in the Senate

The fate of the Senate is much less certain. Democrats would need a net gain of four seats to secure a majority. To do that, they’ll have to defend the vulnerable seats they currently hold in swing states while also flipping at least a couple seats in typically Republican states.

Polls suggest that control of the Senate could hinge on whether Republicans can hold their ground in conservative states like Texas, Ohio, Iowa, Nebraska and Kansas. It’s also worth paying attention to Michigan, Minnesota and New Hampshire, where the GOP could make up for any losses in Republican-leaning states by flipping Democrat-held seats.

What to watch in races for governor

The list of competitive gubernatorial races looks a lot like the list of competitive Senate races. Democrats are on defense in swing states like Wisconsin, Minnesota and Arizona while also eyeing upsets in red states. The Cook Political Report gives Democrats a slight advantage in three states that currently have Republican governors (Ohio, Alaska and Iowa) and list two others (Nevada and Georgia) as toss-ups.

Just two Democratic-led states (Wisconsin and Kansas) are considered either toss-ups or leaning Republican.

What else is on the ballot?

There is a long list of major ballot measures that will be decided on Election Day. That includes two significant abortion-related initiatives. Idaho will vote on whether to override its strict abortion laws and establish a right to abortion until fetal viability, while Missouri will decide whether to roll back abortion protections that were approved by voters just two years ago.

Four states (Washington, Nebraska, Arizona and Colorado) will consider initiatives that would bar transgender athletes from participating in girls’ and women’s sports. Three states (California, Colorado and Nevada) will decide whether to establish or expand laws requiring voters to show ID when they cast their ballots. Voters in five states (California, Utah, North Dakota, South Dakota and Idaho) are considering proposals that would make it harder for citizen-led ballot initiatives to become law.

There are also some significant races happening at the local level. Twenty-two of the 100 biggest cities in the U.S. will choose their mayors on Election Day. That includes Los Angeles, where moderate Democrat Karen Bass is facing a tough challenge from progressive City Council Member Nithya Raman — who some commentators are calling L.A.’s equivalent to New York City Mayor Zohran Mamdani.

Is it too late to vote?

Maybe not. It depends on your registration status and where you live. The first step is to find out if you’re already registered to vote. You can do that here. If you are currently registered, it may still be possible to vote early or request a mail ballot in your state. You can find out the specific deadlines for your state here or by checking your state government’s voter information website. Info on early voting can be found here

Even if you’re not registered, you may still have a chance to vote. Twenty-one states and Washington, D.C. allow same-day voter registration on Election Day.
