Is political polarization worse than it's been in the past?
Short answer: Compared to most of the 20th century, yes—U.S. politics is more polarized today. But it isn’t clearly “worse than ever” if you look back to the 19th century and the Civil War/Reconstruction era.
Helpful distinctions:
•Elite (Congress) polarization: Roll‑call voting shows the two parties have been drifting apart steadily since the late 1970s. By the 2010s–2020s, the distance between Democrats and Republicans in Congress was the largest in at least a century. Most of the movement has been Republicans moving right, with Democrats moving left more modestly. This is near a modern peak.
•Public (mass) polarization:
•Policy views: Many Americans still hold a mix of left/right positions. There’s more “sorting” (Democrats liberal, Republicans conservative) than in mid‑century, but large, immovable ideological extremes are not the majority.
•Affective polarization: Feelings toward the other party have grown much colder since the 1980s. This “us vs. them” dislike is near historic highs in surveys, even when issue distances aren’t huge.
•Historical perspective: Mid‑20th‑century America (roughly the 1930s–1970s) was unusually depolarized because both parties contained sizable ideological wings (e.g., conservative Southern Democrats, liberal Northeastern Republicans). Today’s polarization is clearly higher than that era. Compared with the late 19th century and especially the 1860s, however, the nation then faced deeper sectional divides and widespread political violence—so by those benchmarks, today may be less “extreme,” even if it feels more omnipresent.
Why it feels worse now:
•Parties align with social, cultural, and geographic identities, so partisanship maps onto everyday life.
•Nationalized media and social platforms amplify conflict and negative partisanship.
•Close, high‑stakes elections make each contest feel existential, encouraging hardball tactics and legislative gridlock.
Bottom line: As of 2026, U.S. elite and affective polarization are near modern highs and clearly higher than most of the last 100 years, but not necessarily beyond the peaks of the 19th‑century sectional era.
