Is political polarization worse than it's been in the past?
Short answer: mostly yes—depending on what you mean by “polarization,” and compared to which past era.
•In Congress (elite polarization): By roll‑call and ideology measures, Democrats and Republicans are now farther apart than at any time since the late 19th century. There’s virtually no ideological overlap between the parties. So among elites, today is at or near a modern peak.
•Among the public (issue positions vs. sorting): Most Americans aren’t policy extremists across the board, but liberals now sort strongly into the Democratic Party and conservatives into the Republican Party. There are far fewer “conservative Democrats” or “liberal Republicans” than in the mid‑20th century.
•Affective/social polarization: Dislike and distrust of the other party are at record highs in the survey era (post‑1950s). People are more likely to see the other side as a threat, and social ties increasingly line up with partisanship.
•Elections/behavior: Ticket‑splitting has fallen, outcomes are more nationalized, and primary electorates and safe districts tend to reward more ideologically consistent candidates.
•Historical perspective: The 1850s were worse on the ultimate metric—system breakdown and widespread political violence culminating in the Civil War. The late 1960s–early 1970s also saw more routine political violence than today. But compared with the unusually low‑polarization period from roughly the 1930s–1970s, today is much more polarized on almost every dimension.
Bottom line: U.S. elite polarization is the highest in over a century; public animus is the highest since we’ve measured it; but we’re not at antebellum levels of open conflict. If you meant a country other than the U.S., or a specific dimension (Congress, media, public attitudes), tell me and I’ll tailor the answer.
