Uncertainty dominates presidential campaign’s final stretch

Never before have such dire variables loomed over the closing weeks of an election. Each side cast the other as an existential threat to America’s future as they offered voters starkly different versions of reality over the last two weeks of carefully scripted Democratic and Republican conventions.
