Two Supreme Court rulings last week that dramatically change the law are profound reminders that presidential elections matter enormously for all of us. Like so many of the court’s recent actions, these were 6-3 rulings, with the three justices appointed by President Trump in the majority. These decisions — as with the overruling of Roe v. Wade and the expansion of gun rights in recent years — simply would not have happened if Hillary Clinton had won the presidency in 2016 and she had picked three justices.
