Is political polarization worse than it's been in the past?
Both sidesSays it is contested
Short answer: It depends what you compare and how you measure it.
•In Congress (elite polarization): By roll‑call voting measures like DW‑NOMINATE, party-line distance is at or near its highest levels since the late 19th/early 20th century. There’s now almost no ideological overlap between Democratic and Republican members. So compared with roughly 1930–1980, polarization among elected officials is clearly worse today (as of 2026).
•Among the public: Americans aren’t dramatically more “ideologically” extreme on most policy scales than in the past, but “affective” polarization—dislike and distrust of the other party—has risen sharply since the 1980s. People’s partisanship now aligns more closely with identity, geography, religion, race, media diet, etc., which makes cross‑party social ties rarer and negative partisanship stronger.
•Historical perspective: If you zoom out further, today isn’t unprecedented. The 1850s–1870s (slavery/Civil War/Reconstruction) and parts of the 1890s–1900s featured fierce party conflict, sectional realignment, and far more political violence than today. What was unusual was the mid‑20th‑century “low polarization” era (roughly the New Deal through the 1970s), when the parties were ideologically mixed—especially on civil rights—and bipartisan coalitions were common.
•So is it “worse than it’s been”? Compared with the last 50–70 years, yes: elite polarization and mutual animosity among voters are higher now. Compared with the most conflictual periods in U.S. history, it’s severe but not unmatched—today’s polarization is mostly institutional/gridlock-oriented and affective, not (yet) at the levels of widespread organized political violence seen in the 19th century.
