In our time, polarization has not only grown sharper but has even become its own justification. In the spring of 2018, a poll by the Pew Research Center registered yet another marker in the long series of milestones on the road to ungovernability: Democrats are now just as averse to compromise as Republicans. Only a minority in both parties (46% of Democrats, 44% of Republicans) told Pew they “like elected officials who make compromises with people they disagree with.” The essence of the U.S. Constitution is to require compromise as a condition of governing. In rejecting compromise, Americans are rejecting governance. The United States and other countries have been down this road in the past, and the results are never good.
