Is political polarization worse than it's been in the past?
Leans yesSays it is contested
Short answer: Compared with most of the 20th century, yes—by several key measures the U.S. is more polarized today. But relative to some earlier eras (e.g., the Civil War/Reconstruction period), it’s not unprecedented. It also depends on what you mean by “polarization.”
How it’s worse now (vs. roughly 1930s–1970s):
•Elite/Congressional polarization: The two parties in Congress are farther apart ideologically than at any point in the modern statistical record, which shows a steady rise since the late 1970s/early 1980s.
•Affective polarization: Voters’ feelings toward the other party have grown markedly colder since the 1970s; negative partisanship (voting more “against” the other side) is stronger.
•Social sorting: Ideology, race, religion, education, and geography now line up more cleanly with party identity, reducing cross-cutting ties and making everyday life feel more partisan.
Where it’s more mixed:
•Issue positions: On many policy questions, the public hasn’t moved to extremes as much as it has sorted into parties; the average Democrat and Republican disagree more consistently, but most individuals aren’t far-left or far-right on every issue.
•Perceived vs. actual distance: People often overestimate how extreme the other side is, which can amplify conflict even if policy gaps haven’t exploded.
Historical context:
•Mid-20th century America (especially the 1950s–1970s) was unusually depolarized because both parties contained sizable ideological wings; that “low-polarization” baseline can make today look especially severe.
•Earlier periods—especially the 1850s–1870s and, to a lesser extent, the late 19th century—featured polarization and conflict that rival or exceed today by some measures.
Drivers most researchers point to:
•Party realignment and ideological sorting since the Civil Rights era
•Nationalization of politics and media fragmentation
•Closed/safe primaries and gerrymandered or geographically safe districts
•Rising negative partisanship and elite strategic choices
•Broader forces like economic inequality and cultural change
