Before the end of the year, Amy Coney Barrett will probably be sworn in as a Supreme Court justice — and she may serve for decades. She will have been appointed by an impeached president who lost the popular vote in 2016 and may well continue in office after losing it again in 2020. She will almost certainly be approved by senators representing less than 45 percent of the American population.

Our nation is moving even deeper into minority rule: The House aside, the U.S. government is controlled by the less popular party in a polarized two-party system. We may call this unfair, but that would trivialize the problem. It is entirely permissible under the Constitution, and it is dangerous. When the majority of a nation’s citizens can’t get its candidates elected or its preferred policies passed, the government’s legitimacy is compromised and destabilizing pressure begins to build.

The tendency toward minority rule in the United States, present since the founding, has become more acute. That’s certainly true in the Senate: California has 68 times as many residents that Wyoming has, but the same number of senators. The disparity in population size between the biggest and smallest states is far greater than anything the founders knew.
