Divided Government and Partisan Polarization


A divided government makes it difficult for elected officials to achieve their policy goals. This problem has gotten worse as U.S. political parties have become increasingly polarized over the past several decades. They are both more likely to fight with each other and more internally divided than just a few decades ago. Some possible causes include sorting and improved gerrymandering, although neither alone offers a completely satisfactory explanation. But whatever the cause, polarization is having negative short-term consequences on American politics.
