Democrats Have Been Winning Big in Special Elections

Nathaniel Rakich: “On its own, no — any single special election can be influenced by any number of factors, including candidate quality or parochial issues. But Democrats have been posting special-election overperformances of that magnitude all year long, in all kinds of districts. And on average, they have won by margins 11 points higher than the weighted relative partisanship of their districts.”

“That’s more than just an impressive streak — it’s a potential sign of a Democratic wave election in 2024. In each of the past three election cycles, a party’s average overperformance in all special elections in a given cycle has been a close match for the eventual House popular vote in the eventual general election — albeit a couple of points better for Democrats.”
