This November’s election promises to be one of the more contentious presidential races in recent American history. Donald Trump has compiled a controversial record in both domestic and foreign policy, seeking to reorient not only the Republican party but also America. In the new issue of the National Interest in a cover story entitled “Who’s Worse” about Trump and Joe Biden, Dimitri K. Simes and Dov Zakheim assess the candidates.   Simes is President and CEO of the Center for the National Interest. Zakheim, who served as Under Secretary of Defense (Comptroller) during the George W. Bush administration, is Vice-Chairman of the center. Jacob Heilbrunn, Editor of the National Interest, will moderate the discussion. Both authors believe this will be an important election. And both suggest that America is facing grave dangers. But they disagree on where these dangers emanate from. Simes contends that a second Trump term could be more successful than the first and, above all, that the sharp move toward left-wing authoritarianism in the Democratic party renders it imperative that Joe Biden not replace Trump as president. Zakheim, by contrast, excoriates Trump for his record on domestic and foreign policy, concluding that he will go down as one of the worst presidents in American history.
