Terrible leaders can knock nations off course. Venezuela is falling apart because of the obstinance and delusions of Hugo Chávez and his successor. Argentina is finally coming out of the chaos created by Cristina Kirchner and several of her predecessors. Trump could be our Chávez, our Kirchner. We cannot take that risk. This paper has not endorsed a Democrat for president in its 148-year history. But we endorse Clinton. She’s the safe choice for the U.S. and for the world, for Democrats and Republicans alike.
