Joe Biden is leading in the national polls. But if the lesson of the last U.S. election is any guide, we know the Democrats still have a long road to victory, and four more years of Donald Trump is in the realm of possibility. In this interview, Jim Sciutto, CNN's chief national security correspondent, anchor of CNN Newsroom and author of The Madman Theory, speaks with Adrian Morrow, Globe and Mail U.S. correspondent based in Washington. They discuss the performance of the candidates to date, their potential paths to victory, their plans for governing, and how the American people will ultimately decide as they head to the ballot box on November 3.
