Is political polarization worse than it's been in the past?
Short answer: Compared with the mid–late 20th century, yes—polarization in the U.S. is markedly higher today. Compared with the whole sweep of U.S. history, it’s high but not unprecedented: the 1850s–60s (Civil War era) and, in some ways, the late 19th century were worse.
How it’s worse now (vs. recent decades)
•Congress: Party-line voting and ideological distance between Democrats and Republicans have risen steadily since the late 1970s and are now at or near modern-era highs.
•Affective polarization: Ordinary partisans like and trust the other side less than in the 1970s–90s; people are more reluctant to socialize, date, or work with out‑partisans.
•Sorting: The parties are more internally homogeneous and socially distinct (by ideology, education, religion, race, and geography), so fewer conservative Democrats or liberal Republicans remain.
What’s more mixed
•Mass-policy extremism: Average voters aren’t uniformly more extreme on every issue; rather, they’re more consistently aligned with their party and more negative toward the other side.
•Violence: Today’s climate includes troubling incidents and threats, but it does not match the large-scale political violence of the Civil War/Reconstruction eras and was different in character from the widespread unrest of the late 1960s.
Historical perspective
•Worse than: the relatively low-polarization “mid‑century” period (roughly the 1930s–1970s), which was an anomaly created by unusual cross-party coalitions.
•Not uniquely worst: the sectional breakdown of the 1850s–60s and the fiercely partisan, sometimes violent, late 19th century.
Bottom line
•If you mean today versus the last 50–70 years: yes, polarization is worse, especially in Congress and in how partisans feel about each other.
•If you mean today versus all of U.S. history: no—earlier eras (notably the 1850s–60s) were more polarized and far more violent.
If you’d like, I can share specific indicators (e.g., congressional DW‑NOMINATE scores, long‑run survey “feeling thermometer” trends, or international indices) to put numbers to these points.
