Donald J. Trump was considered an outsider and long shot from the start. An American businessman and reality-show host, he announced his candidacy for president of the United States in June 2015. With no real political experience, it looked certain that his opponent, former Secretary of State and Washington insider Hillary Clinton, had the leading edge. Still, it became one of the most contentious presidential races in U.S. history. In the end, the American people voted for Trump Nation.
