Is political polarization worse than it's been in the past?
Short answer: It depends what you mean by “worse,” but in the United States polarization today is near a modern-era high on several fronts—though not unprecedented in all of U.S. history.
How it compares by dimension
•Elite (Congress): Party-line voting and the ideological gap between Democrats and Republicans have climbed steadily since the late 1970s and are now at or near the highest levels seen since at least the early 20th century. There are far fewer cross-party moderates than in the 1970s–1980s.
•Public opinion on issues: Americans are more “sorted” by party than in the 1970s—liberals are more likely to be Democrats and conservatives Republicans—but the average voter still holds some mixed views. So issue polarization has risen, but less dramatically than in Congress.
•Affective polarization (how partisans feel about the other side): This has increased sharply since the 1980s. Dislike and distrust of the opposing party have grown faster than differences on specific policies.
•Social and geographic sorting: Since the 1990s, party identity has lined up more tightly with race, religion, education, and where people live (urban vs. rural), which makes everyday interactions more partisan and conflictual.
Historical perspective
•Worse eras did exist: The 1850s–1870s (slavery, Civil War, Reconstruction) and parts of the late 19th century featured extreme sectional and party conflict, often with widespread political violence. The 1960s–1970s also saw higher levels of political violence than most years since 2000.
•Compared with the mid-20th century (roughly the 1930s–1970s), when parties were more ideologically mixed and cross-party coalitions were common, today’s polarization is clearly higher.
Why it feels intense now
•Nationalized politics, partisan media and social platforms, closed/low-turnout primaries, gerrymandering in some states, and tighter alignment between party and social identity all strengthen “us vs. them” dynamics, even when issue gaps aren’t uniformly huge.
Bottom line: It’s likely the most polarized the U.S. has been in many decades—especially in Congress and in negative feelings between partisans—but not the most polarized ever if you include periods like the 1850s–1870s.
