Section: Baseline

6/x

Democrats won 215 US House seats in 2024.

This will be the baseline for comparisons that discuss how many additional seats Democrats need to win in 2026 to perform as well as they have in previous elections, when Democrats performed well in the House.

7/x

I will rely on a table of US House results for elections from 1990 to 2024, and its accompanying graphs, that I first published in "Republicans retain House control" in January 2025, about the results of the 2024 House elections.

I originally obtained the data in that table from Wikipedia, which I believe to be a reliable source for data about historical election results.

This table shows how many seats Democrats, Republicans, and Independents won in the US House of Representatives, every two years, from 1990 to 2024.

I will also use the forecasts for US House races compiled by the Cook Political Report.

Both the Cook Political Report and Sabato’s Crystal Ball publish forecasts for various races that describe how likely Democrats or Republicans are to win, using tossup, lean, and likely designations.

11/x

The expert forecasts from Cook Political Report and Sabato’s Crystal Ball are free and open to the public.

It’s a lot easier to use one of these resources for my political analysis, at a time, than to try to use both simultaneously.

I primarily used forecasts from Sabato’s Crystal Ball during my coverage of elections in 2024.

This article will instead use forecasts from the Cook Political Report.

Here are the forecasts for US House races from the Cook Political Report, as of March 12, 2026.

Some of the races in the screenshot above are described as open seats, which means the elected official currently representing the district is not running for reelection, at least not in the district they currently represent.

15/x

The results of the 2025 elections and the results of recent special elections indicate Democrats are positioned to perform well in the 2026 midterms.

Now, let’s explore just how well Democrats could do in 2026 in the US House, by examining several scenarios, in ascending levels of optimism for Democrats.

Section: The Bare Minimum

18/x

There are 435 seats in the US House of Representatives.

That means 218 votes are required to obtain a majority in the US House, if all members are present and voting.

19/x

Democrats won 215 US House seats in 2024, which means they only need to flip three seats to win a majority in the chamber, securing House control.

20/x

But given the current political climate, fueled by a narcissistic, idiotic, tyrannical buffoon of a president, Democrats will likely do much better than that.

Section: Cook's Median Prediction

22/x

The Cook Political Report considers 212 House seats to be Solid Democratic, Likely Democratic, or Lean Democratic.

Cook considers 206 House seats to be Solid Republican, Likely Republican, or Lean Republican.

23/x

#Democrats #Republicans

Cook classifies 17 House seats as tossups.

If we divide these tossup races evenly, Democrats and Republicans would each receive 8.5 additional seats.

This analysis is for Cook’s median prediction, which produces a fractional result.

In practice, a seat would not be split by partisan affiliation, as the following analysis might suggest.

24/x

Adding these tossups to the partisan totals, Cook’s median prediction is for Democrats to win 220.5 seats, and Republicans to win 214.5 seats.

This would give Democrats only two, and a half, more votes than the 218 they need to secure the House majority, if all members are present and voting.

25/x

Democrats won 215 seats in 2024, so they would only need to flip five, and a half, seats to reach Cook’s current median prediction.

Put another way, Cook is currently predicting that Democrats will only flip five, and a half, House seats in 2026.

26/x

Given the current political climate, I believe the Cook Political Report is likely underestimating Democratic chances in House races in 2026.

But it’s also worth bearing in mind that they are experts in election forecasting, and I am not.

Section: 2020 – Democrats’ Most Recent Majority

29/x

In 2020, Joe Biden was elected president, following Trump’s catastrophic mismanagement of the COVID pandemic.

https://jasonbeets.blogspot.com/2021/01/biden-to-improve-us-pandemic-response.html

30/x

#Covid #Pandemic #Health #Disease #Trump #Biden

That was the most recent election where Democrats won control of the US House.

In 2020, Democrats won 222 House seats, and Republicans won 213.

Coincidentally, those numbers exactly flipped in 2022, when Republicans won 222 seats and Democrats won 213.

31/x

#Congress

Democrats would need to flip 7 seats in 2026 to win as many seats as they won in 2020, the last time they held majority control of the House.

32/x

Section: 2018 – Trump’s First Midterm

33/x

Democrats performed particularly well in the US House in 2018, during Trump’s first midterm.

In 2018, Democrats won 235 seats in the US House.

Democrats would need to flip 20 seats in 2026 to perform as well as they did in 2018.

I find this outcome to be the most likely of the historical comparisons we will discuss today.

34/x

#Graph

I created the graphs in this article using Flourish, a website that allows users to create compelling visual aids.

https://flourish.studio/features/

35/x

Let’s examine what this would look like in practice.

To win 235 seats in 2026, Democrats would need to win all of the Solid D, Likely D, Lean D, Tossup, and Lean R races, as well as two Likely R seats.

36/x

I find the chances that Democrats perform as well as they did in 2018, in Trump’s first midterm, to be a reasonable prediction.

Therefore, I believe Democrats are positioned to perform better in 2026 than Cook’s forecasts predict.

37/x

But that being said, I have consistently been optimistic about Democrats’ political chances, even in elections where Democrats didn’t end up doing particularly well.

Section: Comparing 2018 and 2006

39/x

In many ways, Trump’s reelection in 2024 feels reminiscent of George W. Bush’s reelection in 2004.

So it would seem right that Democrats would be positioned to perform well in Trump’s second midterm, just as they did in Bush’s second midterm.

40/x

But Democrats actually won more seats in the US House in 2018, than they did in 2006.

Democrats won 235 House seats in 2018, whereas Democrats only won 233 House seats in 2006.

41/x

If Democrats perform as well in the House in 2026 as they did in 2006, they would have two fewer seats than they had after 2018.

Democrats would need to flip 18 seats to win a majority as large as they had after the 2006 election.

42/x

Democrats would need to win all of the Solid D, Likely D, Lean D, Tossup, and Lean R races to win 233 seats, and match their performance from 2006.
