As the nation approaches the 2026 midterm elections, rapid social, economic, and technological change is reshaping political attitudes. To understand an electorate that traditional partisan and demographic categories alone cannot capture, LSG launched a national study this summer.
Welcome to The Emerging Electorate.
Drawing on proprietary research among 2,000 likely voters nationwide, we identified eight groups with distinct demographic, political, and attitudinal characteristics. The segmentation offers a more nuanced picture of the perspectives and priorities shaping the midterms.
The Progressive Wing, Alienated Left, and Moderate Democrats form much of the Democratic-aligned coalition. MAGA Republicans, MAHA Enthusiasts, and Non-MAGA Republicans comprise the new Republican base.
The most politically fluid groups, however, sit closer to the center: the Disaffected Right and Anti-Populist Centrists. Their weaker attachment to partisan voting patterns makes them critically important to understanding the electorate in 2026.
The Midterm Elections
In our survey, Democratic candidates lead Republicans by nine points on the generic congressional ballot among likely voters. Among swing voters, 48% favor Democrats, giving them a 14-point lead over Republicans with this highly sought voter segment.
Much of this dynamic is being driven by the electorate’s most persuadable, centrist segments. The Disaffected Right leans conservative but distrusts the American political system and its institutions. While 67% voted for President Trump in 2024, 60% now disapprove of his performance. Most still plan to vote Republican in the midterms, but more than one-third (36%) do not, including 22% who plan to vote Democratic. Inflation and the economy are their defining concerns: 68% disapprove of Trump’s handling of inflation, and 56% disapprove of his handling of the economy.
Anti-Populist Centrists show a different but similarly fluid pattern. Defined by their greater optimism about the future and greater trust in institutions, this cohort generally approves of President Trump (72%). Although 62% voted for Trump in 2024, 43% do not currently plan to vote Republican in the midterms, including 37% who plan to vote Democratic. This group is not uniformly Republican: 32% voted for Harris in 2024. Its priorities span health care, inflation, the economy, immigration and debt, making presidential approval an imperfect guide to its congressional vote.
These two groups stand out because they combine a history of Republican voting with an openness to Democratic candidates, making them especially important to the midterm outlook.
To test the durability of the nine-point Democratic lead, we modeled what would happen if historically Republican-leaning voters in these two groups who now plan to vote Democratic returned to the Republican column. They account for about 2% of likely voters; all other responses remained as recorded.
If half return, the Democratic lead narrows to seven points. If all return, it narrows to five. If Republican-leaning members of these groups who now support a third-party candidate also shift to Republicans, the lead narrows to about three points. Democrats lead in every scenario, but the spread shows how a small, identifiable group of voters could materially impact the race.
How much of that gap closes depends on whether these voters follow their current frustrations or their past voting habits – and whether the candidates and their campaigns resonate with them.
Democrats have the advantage for now. Campaigns seeking to reach these voters should first understand what drives them. Read LSG’s full study, The Emerging Electorate, on our website.
Survey Methodology: LSG conducted an online survey of n=2,000 U.S. likely voters matched to L2 voter file data from May 18 to June 1, 2026. Results were weighted by race, party identification, income, age, and region using Census-matched midterm turnout records and voter file data. The margin of error is ±2.2 percentage points.
