Is political polarization worse than it's been in the past?
Short answer: In the United States, polarization is very high by modern standards—but “worse than ever” isn’t quite right.
•What “polarization” means:
•Ideological polarization: how far apart the parties are on policy.
•Affective polarization: how much partisans dislike and distrust the other side.
•Sorting: whether ideology, identity, geography, and party line up more tightly than before.
•Where we are now (U.S.):
•Among elected officials, the parties are farther apart on roll-call votes than at any point since the late 19th/early 20th century. Cross‑party coalitions are rare.
•Among the public, dislike of the opposing party (affective polarization) has risen sharply since the 1970s. Negative partisanship—voting more “against” than “for”—is common.
•On specific issues, the mass public is more sorted than it was mid‑20th century, but many Americans still hold mixed or moderate views; the gap in elites is larger than in voters.
•Compared with the past:
•Mid‑20th century (roughly the 1930s–1970s) was unusually low-polarization because each party had sizable ideological wings that overlapped.
•Earlier eras (e.g., the 1850s run‑up to the Civil War, parts of Reconstruction, the 1890s) saw extreme elite conflict and, at times, political violence—so today is not the most dangerous period in absolute historical terms, even if day‑to‑day partisan hostility feels intense.
•Why it’s risen:
•Long‑term party realignment (e.g., over civil rights), nationalized elections, residential and educational sorting, media and social media environments that heighten outrage, and institutional incentives (primaries, safe districts). Gerrymandering contributes in some places but is not the sole driver.
•Outside the U.S.:
•Many democracies have also seen rising affective polarization, though the pattern varies by country and electoral system; multi‑party systems can diffuse conflict, but they aren’t immune to polarization or gridlock.
If you’re thinking about a specific country, time period, or type of polarization (ideological vs. affective), tell me and I can tailor the answer and share representative data trends.
