Is political polarization worse than it's been in the past?
Short answer (for the United States): by several important measures, yes—polarization today is worse than in much of the 20th century, though not unprecedented across all of U.S. history.
What’s higher now
•Elite (Congress) polarization: Roll‑call voting shows Democrats and Republicans far more separated than they were from roughly the 1930s–1970s; the distance has climbed steadily since the late 1970s and sits at or near modern-record highs.
•Affective polarization: Ordinary partisans like and trust their own side more and the other side less than in past decades; negative partisanship (voting mainly to oppose the other party) has grown.
•Party “sorting”: Ideology, geography, education, religion, race, and urban–rural residence line up with party identity more cleanly than they did mid‑century, reducing cross‑pressures that once encouraged compromise.
•Straight‑ticket voting and nationalized elections: Split‑ticket voting has fallen; federal and state races move in lockstep, leaving fewer incentives for cross‑party cooperation.
Where the picture is more mixed
•Issue positions: On many policy questions, the public still shows overlap; large blocs are not uniformly “far left” or “far right,” even if averages have drifted apart.
•Social media and gerrymandering: Both matter, but patterns also appear where those factors are weaker (e.g., the Senate and statewide offices), suggesting deeper forces like party realignment and primary electorates.
Historical perspective
•Not the absolute worst ever: The 1850s–1870s (run‑up to and aftermath of the Civil War) saw far deeper conflict and political violence. The late 19th century was also highly polarized. Compared to the relatively low polarization of the mid‑20th century, however, the 1990s–2020s mark a sustained rise.
Bottom line
•Compared with the mid‑20th century baseline many people remember, polarization today—especially among political elites and in how partisans feel about each other—is at or near the highest levels measured in the modern era. It’s severe in consequences (gridlock, norm erosion), but not historically unique if you zoom out to the Civil War era.
