Evidence is mounting that the 2026 general election will be one of those increasingly rare occurrences in American politics: a wave election. As Donald Trump hits Nixon-level job approval ratings and the American economy continues to sour, voters across the spectrum are registering their deep discontent with the state and direction of the country.
As of this writing, the national Congressional generic ballot leans 7 points towards Democrats. By comparison, the Congressional generic ballot at the same period in 2022 leaned towards Republicans by 2.5 points (actual result: R+2.8); in 2018, it leaned towards Democrats by 7.3 points (actual result: D+8.4). A 7-point party advantage would thus be roughly similar to the famous Democratic “blue wave” election of 2018.
A wide array of polling shows a similar pattern here in North Carolina. A survey of all credible statewide polling in 2026 suggests a generic ballot advantage of approximately 4.3 points Democratic:
This raises a natural question: what would be the consequences be of such a shift, or a larger or smaller one, for the North Carolina state legislature?
Modeling election outcomes
To model the range of possible outcomes for the 170 seats in the North Carolina state legislature, consider the following tool, which allows users to visualize the impacts of different election environments:
We estimate that a 4-point shift in the two-party vote for the North Carolina state legislature could flip 9 seats (7 in the House, 2 in the Senate). Were that to happen, it would break the Republican supermajority in the State Senate, but still leave Democrats well short of a simple majority in either chamber.
This is not a hard-and-fast prediction. Legislative elections are variable, and close ones often hinge on intangible factors like candidate quality and luck, which of course cannot be modeled. Instead, this model shows what the likely baseline partisan lean of each district could be under different conditions. For example, House District 59 is an R+3 district (it leans Republican by about 3 points), but in a D+4 election year, we estimate its lean will be reduced to just R+0.1 - a virtual dead heat. This could equally mean a Democratic flip, or a Republican hold. (Read on for more about this methodology.)
North Carolina’s state legislative maps are an aggressive Republican gerrymander. This systematically protects Republican districts and makes Democratic ones more vulnerable, and thus even in a strong Democratic cycle, Democrats will win fewer seats than Republicans will in a mild Republican-leaning one.
In the House, the Republican gerrymander “breaks” in roughly the D+5-6 territory. This means that in order to win a majority of the State House, Democrats would need to over-perform by about 5-6 points statewide, relative to 2024.
In large part due to the county grouping process, the State Senate is much easier to gerrymander, and thus it is significantly more rigged. The Republican gerrymander there does not “break” until a D+10 wave - and even then, that would only give Democrats a 1-seat majority.
Modeling methodology
A tempting approach to estimating the impact of an election cycle’s partisan shift would be to simply apply a single figure to all districts equally. That approach would be easy, but also methodologically wrong.
All voters are different, and some behave differently than others. Some voters and districts are “swingier” than others - that is, more likely to change their voting behavior from one election to the next. This is the essence of the concept of “elasticity.” Higher elasticity indicates a district that tends to shift more in an election than the average statewide, while a district with lower elasticity shifts less.
Thus, to accurately model the likely impact of a single statewide shift, one has to calculate district elasticity. State legislative districts tend to be less elastic overall than statewide, top-of-the-ticket races. We thus apply a significant discount to top-ticket elasticity just to be conservative. This is why a 1-point shift in either direction does not necessarily move each district the same amount.
Steep odds
Many Democrats reasonably expect a strong election year in 2026. While it is possible that trends could reverse, and the generic ballot could narrow, it’s equally possible that it could further widen - time will tell.
In any case, in North Carolina, that wave will still crash upon one of the most odious partisan gerrymanders in the country. North Carolina’s state legislative maps are specifically tailored to create and protect a Republican majority, and that is what they will do in all but the most unprecedented wave election. A 4-point Democratic generic ballot advantage will be enough to stave off a Republican super-majority, but probably not take a majority themselves. As long as the North Carolina State Supreme Court defends Republican partisan gerrymandering, the voters will just have to wait.
