Is political polarization worse than it's been in the past?
Short answer: In the United States, yes—by several standard metrics it’s worse than in living memory, though not necessarily worse than the late 19th century or the Civil War era depending on what you measure.
How scholars measure it (and what those show today):
•Elite/legislative polarization: Voting records in Congress show the parties are farther apart and overlap less than at any time since the late 1800s. Party-line voting is routine and cross-party coalitions are rare.
•Affective (emotional) polarization among the public: Since the 1980s, Democrats and Republicans have grown much more hostile to each other (seeing the other side as a threat, not just “wrong”). Social ties—friendships, dating, workplaces, churches—are more sorted by party than a few decades ago.
•Mass ideological polarization: Ordinary Americans are more “sorted” (parties align more cleanly with ideology and identity), but the average voter isn’t as ideologically extreme as party elites. So animosity has grown faster than issue extremity.
Historical perspective:
•Compared with the mid-20th century (roughly the 1940s–1970s), today’s polarization is clearly higher. That earlier period looked moderate in part because each party contained both liberals and conservatives (e.g., Southern conservative Democrats and liberal Northeastern Republicans).
•Compared with the most fraught periods—The Civil War and Reconstruction, or moments of intense conflict in the late 19th century—today’s polarization is institutionally severe but generally less violent. So “worse than ever” depends on whether you mean elite party separation, public hostility, or outright conflict.
Why it’s risen:
•Long-term party realignment (especially around race, religion, region, and education)
•Media fragmentation and social media
•Nationalized politics and primary electorates that reward ideological purity
•Geographic sorting and gerrymandering (a secondary but contributing factor)
•Rising negative partisanship and, many argue, economic and status anxieties
If you want, I can pull specific time-series charts (e.g., congressional DW-NOMINATE scores or Pew trends on affective polarization) or look beyond the U.S. to compare other democracies.
