Opinion | Congress should stop second-guessing states

Congress should get out of the business of second-guessing state-cast votes, yes. But wouldn’t it be much more difficult to undermine an electoral vote system predicated on proportionality rather than winner-take-all? In a proportional distribution of electoral votes, no candidate would win all of the electoral votes in a state. In 2016, then-Republican presidential nominee Donald Trump would have had to split Michigan, Pennsylvania and Wisconsin with Democratic presidential nominee Hillary Clinton, and Ms. Clinton wouldn’t have walked away with all of California and New York.
