Is political polarization worse than it's been in the past?

Both sidesSays it is contested

Political Polarization: Historical Context

This is genuinely debated among historians and political scientists, with the answer depending on what you're measuring and where.

Case for "yes, it's worse" (at least in recent memory):

•In the U.S., partisan affective polarization (how much people dislike the opposing party) has risen sharply since the 1980s-90s by most measures

•Split-ticket voting has declined significantly—fewer people vote for different parties for different offices

•Geographic and social sorting has increased—people increasingly live near, marry, and befriend those who share their politics

•Congress shows increased party-line voting compared to mid-20th century

Case for "not unprecedented":

•The lead-up to the U.S. Civil War involved actual political violence, caning on the Senate floor, and eventual secession—arguably far more severe

•The 1960s-70s saw assassinations, bombings, and mass civil unrest tied to political divisions

•The Gilded Age had extreme wealth-based political conflict and violence (labor disputes, etc.)

•Many democracies have survived worse: Weimar Germany, various Latin American countries in past decades

What seems most defensible:

•Current polarization is severe by the standards of roughly 1950s-1990s, which may have been an unusually low point historically (partly due to Cold War unity, New Deal consensus, etc.)

•What's more novel now may be affective polarization (personal animosity) combined with media fragmentation, rather than polarization over policy substance

•Some argue the "for its era" framing matters: media speed and social media amplification make current polarization feel more intense even if not historically unique in degree

Bottom line: It's likely worse than the mid-20th century "consensus era," but probably not unprecedented in the broader sweep of history. What might be more accurate to say is that a period of unusual comity is ending, not that we're in uniquely dangerous territory.
