Is political polarization worse than it's been in the past?
Short answer
•Among elected officials, yes: polarization in Congress is at or near its highest levels since the late 1800s.
•Among the public, it’s complicated: Americans are much more “sorted” by party and more hostile to the other side than in the 1970s, but they are not uniformly more extreme on every policy issue.
•Compared with the most perilous eras (for example, the 1850s before the Civil War), today’s polarization is severe but not unprecedented in U.S. history.
What “worse” can mean
•Ideological polarization (issues): How far apart the parties are on policy. In Congress, distances have grown steadily since the late 1970s and the old overlap (conservative Democrats, liberal Republicans) largely disappeared by the 2010s.
•Affective polarization (feelings): How much partisans dislike and distrust the other side. Since roughly the late 1980s, negative feelings have risen sharply and now exceed positive feelings for one’s own party in many surveys.
•Sorting: People’s identities (ideology, religion, race, geography, education) line up with party more tightly than in, say, 1960–1980, making cross-party coalitions rarer even if average issue views haven’t moved as much.
How today compares to the past
•1850s–1860s: Open breakdown of the party system and civil war—clearly worse on societal stability.
•1890s and early 1900s: Intense regional and class divides, but parties were less ideologically consistent than today.
•1930s–1960s: Strong cross‑party coalitions (e.g., New Deal Democrats plus some Republicans; conservative Southern Democrats with Republicans on civil rights opposition), so less ideological polarization despite big fights.
•1970s–present: After civil-rights realignment (1964–1968), ideological distance and party-line voting rose steadily. By the 2000s–2020s, Congress reached modern highs; in the public, affective polarization became very high even as many issue opinions moved modestly.
Why it has risen since the 1970s
•Party realignment on race and region after the Civil Rights Act (1964) and Voting Rights Act (1965).
•Nationalized media and information ecosystems (cable talk formats from the late 1980s; internet/social media since the 2000s).
•Primaries, donor incentives, and safe seats that reward partisan purity; geographic self-sorting by education and density; gerrymandering contributes in some places but isn’t the sole driver.
•Rising salience of identity-inflected cultural issues alongside widening urban–rural and education divides.
Bottom line
•If by “worse” you mean elite party distance and mutual partisan animosity, today (2020s) is near a modern peak compared with the mid‑20th century. If you mean threat of systemic collapse or civil conflict, the 1850s–1860s were worse. The texture of polarization has changed: fewer cross‑cutting identities and more negative partisanship make today’s politics feel more zero‑sum even when average policy views haven’t moved as far.
If you want, I can pull specific recent charts (e.g., congressional DW‑NOMINATE trends, Pew trends in affective polarization) and walk through them.
