This is an upload of a guest appearance on Paul Krugman’s Substack, recorded September 30, 2026. Watch this video on gelliottmorris.com. Paul Krugman had David Nir, who co-hosts the SIN podcast with me, and me on his weekly interview show this Thursday, and the video is out this morning. Paul has graciously agreed to let us repost the video interview and transcript here. In this recording, we talk about (obviously) the state of the midterms — particularly the now-quite-rosy odds of the Democrat taking the House and Senate in November. We also talk about (go figure) the economy, and the counterintuitive finding from historical midterms that economic growth and other objective indicators typically don’t predict midterm outcomes well. What matters far more than any indicator is the label of the party in control of the White House. Of course, when everyone is saying they're mad about prices and only ~20% say the incumbent party is handling the issue well, that tends to have an effect electorally too. We also get into the chance of a large polling miss this year, like in some notable recent elections. I give a reminder that tools like election forecasting models, when done well, can represent uncertainty in the election given measurement error in the indicators. Thanks to Paul and David for a great discussion. Here are some links, and I’ve pasted the transcript below for easy reading. Elliott Transcript Paul Krugman: Like almost everybody I know, I spend about 17 hours a day thinking about the midterms, and I’ve got G. Elliott Morris and David Nir from Strength in Numbers and The Downballot here to talk to me about: What do we know? What’s going to happen? What are the indicators? And then maybe some broader issues about what the heck we think is going on in U.S. politics. So, hi, guys. Welcome. Elliott Morris: Hey, thanks, Paul. David Nir: Paul, it’s a pleasure. Krugman: So, yeah, as we record this, I guess it’s one month and two days before the midterms, and if I believe you guys, the polling and other indicators, which David will talk about, seem to be almost kind of shocking right now. Elliott, I just looked at your Fifty Plus One post, and I believe you now have 99% odds of Democrats controlling the House. Morris: Yeah, well, it’s October, Paul. So we’re in what I consider spooky probability territory. 99% is when you start to go, “I hope these models are parameterized correctly.” Look, the way to unpack this: Our model at 50 Plus One shows a 99% chance that the Democrats will win 218 seats or more. 99% seems very large. As the forecaster, I don’t want to be wrong on the 99, but it makes sense when you look at the numbers on paper. So, let’s take 2018 as a comparison case. That’s when Democrats won 235 seats in the House. That year, the generic ballot—which is a question that asks people how they will vote in their local congressional district, for which party they will vote—that has Democrats up somewhere between 8 and 9 points. Democrats won in 2018, leading the polls by about 8 or 9 points. They actually won the House popular vote by seven and a half points or so, if you account for some weirdness with, like, uncontested seats. So we are in a more favorable environment, if the polls are right, than 2018. And we also have a lot of other district-level indicators pointing the same way. Krugman: But, I mean, the gerrymandering was fairly extreme before this, and if we go back to the beginning of this year, it was looking a little iffy, if I recall. Morris: Yeah. So gerrymandering seems to have shifted maybe a handful of seats at most to the Republicans, accounting for some pretty rosy polling, for example, in South Texas and in Florida for the Democrats, where there’s been a larger shift than the national shift, which is about 10 or 11 percentage points. So if we are around eight points, our model says Democrats need to win the House popular vote by about three and a half points. So there’s room for the polls to be wrong by about five. The average expected error for the polls at this point, 30 days before the election, is about three and a half percentage points. So we’re looking at a larger-than-average error in the polls. And then if you account for other indicators, district-level surveys, the race raters like we do, that’s how we get up to that 99. But yeah, I acknowledge this is a very, very large probability. Nir: And Paul, just to address your point about the gerrymandering, which did heavily favor the GOP, it’s important to remember that Republicans were not doing that from a position of strength. They were doing it from a position of weakness, precisely because they knew that they were facing a very difficult midterm election. And they definitely—I can say this with certainty—definitely will not pick up, they will not flip, all of the seats that they targeted in Texas and Florida and elsewhere. And that has a lot to do with the quality of candidate recruitment on both sides. And also, in particular in Texas and Florida as well, has a lot to do with Latino voters moving back against Trump after moving heavily for him in 2024. So, 2024 in a lot of ways was a high watermark. And so when you’re looking at how Trump performed in these districts two years ago, in a lot of cases, expect really a lot of fallback for the GOP. Krugman: Tell me if I’m being underinformed here, but my understanding is that the gerrymandering was based, at least partially, on the assumption that the Hispanic shift towards Trump that took place in ‘24 was an enduring feature of the landscape, and that it all kind of goes wrong if, as now appears to be the case, it’s not enduring. Right? Nir: That’s definitely what it appears to be. Because if you look at these redrawn districts, and instead of looking at how they went in 2024, if you go back a few years earlier and look at how they performed in 2020, when Joe Biden did much better with Latino voters than Kamala Harris did in many parts of the country, they show a much more competitive picture. And so you have Republicans talking about, you know, “Oh, these districts are Trump plus five, Trump plus ten, Trump plus 15.” But that’s 2024. You dial back to 2020, and suddenly we’re talking about districts that Joe Biden won, that Democrats have a real chance of holding on to in 2026. Krugman: Okay. And I want to talk about other indicators, and polling in general. But just a question about the Senate: So now, we’re up into the 70s again for the Senate, right? And that’s a lot less. I mean, the Senate is sort of inherently gerrymandered. States that have about the population of some neighborhoods in the Bronx have as many seats. So, yeah. But that’s also looking pretty strong, right? Morris: Well, speaking of state gerrymandering, don’t get me started about the drawing of the state border of Nevada. I mean, that was a gerrymander, right? So, look, the Democrats have 47 seats right now. They need 51 to have a majority and to overcome JD Vance’s tiebreaker as president of the Senate. So they need four pickups. They look likely, according to our model, to get a pickup in North Carolina, where the former governor, Roy Cooper, is running against the current chair of the Republican National Committee. So that’s what’s on my mind. They look then likely as well to somewhere between a sort of toss-up and a lean Democratic seat in Texas and Ohio, where Democrats have got some good recruits in James Talarico and Sherrod Brown, a former incumbent senator of Ohio. And I should say Democrats are also very likely to hold on to their seat in Georgia, just for what it’s worth. And then we get into the seats that are, like, a lot, a lot tighter. That’s Iowa, currently Republican-held, but where the Democrat, Josh Turek, is leading the polls; Maine, where the polls were somewhat, you know, incredibly wrong in 2020, showing Susan Collins losing to— Nir: Sarah Gideon. Morris: See, this is why we do it together, Paul, right? Krugman: Yeah, I know, it’s okay. Morris: And then there’s Michigan, which seems like it should be a Democratic win in an environment where Democrats are ahead by eight points on the generic ballot. But the race is surprisingly close between Abdul El-Sayed and Mike Rogers. And there’s like a bunch of other reach seats that might be competitive. We can talk about Kansas, where Democrats currently have a polling deficit of under half a point in Kansas. Like, what’s the matter with Kansas? Krugman: Yeah. I mean, objectively, Trump policies, especially a war that’s driven up diesel prices and fertilizer prices and all of that, has been really pretty bad for farm country. But I don’t know to what extent we’re seeing that, to what extent we’re just seeing really just bad Republican recruitment or just general Trump fatigue. Morris: I’ll say one thing about the numbers and then hand it over to David. But the other Plains states—Nebraska, Iowa, and Kansas are the ones I’m thinking of—are all much more competitive than you would expect, given the fact that Donald Trump won these places by, you know, between 10 and 28 percentage points. I think in the case of Nebraska, if I’m remembering correctly. These are all within a point or so in the polls today, and back in 2025, when I was looking at Trump’s approval rating and all of the polling we do at Strength in Numbers. So these are individual interviews from these Plains states. Donald Trump was also much less popular than you would expect, given his margins, and deportations and, and tariffs especially were very unpopular, or even more unpopular than Trump overall in these places. So, I think you’ve triangulated maybe there’s more economic pain in these places. Donald Trump has certainly very publicly pushed for these policies. So I can imagine voters are putting more blame on him directly because of the press conferences for ta
