The Washington Post reports that there was a sharp uptick Friday in the number of Britons Googling basic questions about what the European Union is and what the implications of leaving are. This is a bit like deciding to study after you’ve already taken the final exam. Technically, the Brexit referendum is not binding. Parliament could decide to hold their own vote on whether to leave the European Union. Perhaps they should. Perhaps the U.K.’s leaders owe it to the people to thwart their expressed will.
