What Are The Midterms?

It's Tuesday, November third. Today is the midterm election. If nobody has ever explained that word to you properly, here it is: a midterm is the national election that happens halfway through a president's term, and what it decides is who controls Congress for the last two years of that term.

The president isn't on the ballot. That's the whole point of the name. Which is exactly why people skip it.

What is on the ballot: all four hundred and thirty-five seats in the House of Representatives, thirty-five of the hundred Senate seats, and governors in thirty-six states.

And here's the thing about today that almost everyone gets wrong. It isn't the day the election happens. It's the last day you're allowed to vote in it.

Start with the weirdest fact about American elections: the entire House of Representatives is replaced every two years. Not a third of it. All of it.

That's because House members serve two-year terms. There's no staggered schedule, no half up at a time. Every even-numbered November, all four hundred and thirty-five seats are on the ballot.

The founders did that on purpose. The House was designed to be the body that feels the public mood fastest — the one closest to the voters and quickest to turn over. The Senate was built the opposite way: six-year terms, split into three classes so only about a third come up in any cycle. Which is why the Senate changes slowly and the House can flip in one night.

So the midterm isn't a lesser election. It's the election for the chamber that can block a president's agenda entirely — and it happens while the president is still in office, with two years left to govern.

Historically, the president's party almost always loses House seats in these. That's happened in twenty of the last twenty-three midterms. Not because of a rule, but because of how voters behave: the party in power gets blamed, and the people who voted for the loser last time are more motivated.

Now the part that answers the question you're probably asking: why does the final day get all the attention if voting has been open for weeks?

Because the final day is a deadline, and deadlines are how you organize a national event. In practice, the election has been running for a month.

In 2022, about half of all ballots were cast before Election Day — roughly a third by mail, and another fifth in person at an early voting site. In 2020, during the pandemic, it was closer to seventy percent.

So today isn't when the country votes. It's when the country stops voting. The campaigns know this; that's why they spend the last week chasing people who have already received a ballot and haven't returned it.

Then there's the thing that makes people suspicious every cycle: the result doesn't arrive when the polls close.

Election-night numbers are unofficial and partial. In many states, a mail ballot postmarked by today can arrive days later and still count. Provisional ballots — the ones you fill out when there's a question about your registration — get checked one at a time. Then comes the canvass, which is the boring word for the real work: election officials reconcile every ballot cast against the record of who voted, so the totals match the number of people.

After the canvass, counties certify. Then the state certifies. That takes days in some places, weeks in others.

None of that is a malfunction. It's what counting looks like when fifty states do it separately, by hand and by machine, with rules written by each legislature.

And then the polls, which might be the most misunderstood thing in the entire process.

A poll is a sample. Somebody calls or texts a few hundred or a few thousand people and asks how they'd vote, then weights the answers to look like the country. The output comes with a margin — a range, not a number — because a sample can't tell you exactly what a population thinks.

Which means a poll is a snapshot, not a forecast. It tells you where the race sits this week. It doesn't tell you who wins, and it definitely doesn't tell you whether your vote matters.

Campaigns use them for something much more mundane: deciding where to spend the last few million dollars. If a district is already decided, money goes elsewhere. And the aggregators that average dozens of polls exist because a single poll is noisy and twenty of them are less noisy.

So "the polls say my side loses, so why bother" is mixing up two different things. A poll measures what people say when you ask them. The election measures what they actually do by the deadline.

So today is a deadline. Everything strange about it — the weeks of early voting, the mail ballots still arriving, the count that runs past midnight and then past the week — is what a deadline looks like when fifty states administer it at once.

If you've already voted, you're done. If you haven't, today is the last day that counts.

Stay informed, stay curious, and we'll see you tomorrow.
