How Tennessee 7th's 13-point Democratic shift would look across the nation for 2026
Last week, Republicans won the special election for Tennessee’s 7th Congressional District by 9%, and it has them scared shitless. That’s because the margin was 13% worse than the previous representative and President Donald Trump did in that district.
Normally, Republicans could write off a shift like that by noting that Democrats tend to do better in low-turnout special elections, and that they weren’t predictive in 2023-24. But turnout in the special election was actually higher than in the 2022 midterm electorate. And Republicans can’t chalk the narrow win up to a crummy nominee; newly elected Rep. Matt Van Epps (R-TN) was a pretty generic Republican, while the Democratic nominee had taken some public stances to the left of most voters in the district. In short, Republicans are losing a lot of their own voters, shifting margins by around 13%.
That 13% is a lot, that’s a blue wave-level shift. So that begs the question: What if this special was a preview of 2026? What would a nationwide shift of 13% look like? For starters, it’d mean winning 250 House seats and possibly a Senate majority.
But how would it look at the state level? With 88 state legislative chambers up for election next year we wanted to take a look at how a 13-point swing would manifest itself. How many seats could Democrats win? Could they score any new majorities, or trifectas or supermajorities?
