Is political polarization worse than it's been in the past?
Short answer: Compared to the mid‑20th century United States, yes—polarization is markedly worse. Compared to the late 19th century or the Civil War era, today’s conflict is intense but not unprecedented.
What the evidence shows (U.S.-focused):
•Elite (Congress) polarization: By standard roll‑call measures (like DW‑NOMINATE), the ideological distance between Democrats and Republicans has climbed steadily since the late 1970s and is now at or near a 100‑year high. The 1950s–1970s were unusually low-polarization decades because the parties contained significant liberal Republicans and conservative Democrats; that overlap has largely vanished.
•Mass issue positions: On many individual policy questions, the public has not split into two extreme camps as much as headlines suggest. Average voters are somewhat more sorted (party, ideology, and issue views line up more consistently) rather than uniformly more extreme.
•Affective polarization: Feelings about the other party have grown significantly colder since the 1980s. People are more likely to distrust, dislike, and socially distance from out‑partisans—even when their specific policy views aren’t extreme.
•Geographic and electoral sorting: Fewer competitive districts and more “landslide” counties make general elections less moderating; more action shifts to low‑turnout primaries where highly engaged partisans dominate.
•Violence and democratic stability: Today’s period includes serious flashpoints, but the overall level of organized political violence remains below the peaks of the 1850s–60s and the late 1960s–70s. Still, democratic norms (trust in elections, willingness to accept losses) have weakened compared with the late 20th century.
Bottom line:
•Worse than the mid‑century baseline (roughly 1950–1980), especially among political elites and in how partisans feel about each other.
•Not clearly worse than America’s most polarized historical periods (Reconstruction/Gilded Age; Civil War era), which featured deeper party divides and far more violence.
