Is political polarization worse than it's been in the past?
Yes, by multiple key metrics, political polarization in the United States is higher now than it has been for much of the past several decades (especially since the mid-20th century bipartisan era), and in some elite-level measures it exceeds most of the post-Reconstruction period—though it is not unprecedented in American history and falls short of the existential divisions of the Civil War era.
