In July, the Democratic National Committee engaged some 600 lawyers to litigate the outcome, possibly in every state. No particular outcome of such litigations is needed to set off a systemic crisis. The existence of the litigations themselves is enough for one or more blue state governors to refuse to certify that state’s electors to the Electoral College, so as to prevent the college from recording a majority of votes for the winner. In case no winner could be confirmed by January’s Inauguration Day, the 20th Amendment provides that Congress would elect the next president. Who doubts that, were Donald Trump the apparent winner, and were Congress in Democratic hands, that this would be likelier than not to happen?
