For the first time in its history, the San Diego Union Tribune has endorsed a Democrat for president. The paper published an endorsement Friday, describing Donald Trump’s campaign as an “entertaining show” that threatens to derail the nation if Trump is allowed to win. Calling Trump “vengeful, dishonest and impulsive, the paper’s editorial board warned that “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,” the paper’s editorial board warned. Calling Clinton “the safe choice for the U.S. and for the world," the paper noted that it was breaking with tradition for this election. “This paper has not endorsed a Democrat for president in its 148-year history. But we endorse Clinton."
