Tuesday’s wave election swept Democrats into power in Congress. But the most seismic result for American politics and democracy may come out of the battleground states where Democrats just won trifecta control by taking both state houses and the governor’s mansion: Come January, Democratic legislators will have the votes to elect the next president by the popular vote.

State lawmakers could circumvent the Electoral College by enacting what’s known as the National Popular Vote Interstate Compact. Under the current system, each state gets a set number of electors, and the candidate who wins enough states to accumulate at least 270 electoral votes becomes president. This system allows the winner of the popular vote to lose, as Al Gore did in 2000 and Hillary Clinton again in 2016. But the NPVIC would bypass the Electoral College, with each state that enacts the compact awarding its electors to the winner of the national popular vote. The compact would only take effect once states representing a majority of electoral votes sign on, ensuring that the winner of the national popular vote becomes president.

In April, Virginia became the 18th state to join the compact, bringing the total number of electoral votes pledged under the proposal to 222. On Tuesday, Democrats took trifecta control of state governments in Michigan, Wisconsin, Pennsylvania, Arizona, and Nevada. That’s 61 electoral votes. Add in Alaska, where late-arriving votes are still being counted, and that’s 64. With Virginia on board, only 48 more votes are needed for the compact to reach 270 votes and take effect. The emerging math means there is a real chance that the next president is selected based on the national popular vote.

Heaven forfend! The person who gets the most votes wins? That’s antithetical to democracy and must be stopped.
