YOUNGSTOWN, Ohio - In 2016, Donald Trump was elected president without winning a majority of the popular vote. How did this happen? The U.S., like many countries, has an indirect system for selecting its leader. Based on the popular vote in each state, 538 electors are selected, and they cast their vote for president in December. Based on past history, it is fairly easy to predict which party's electors will win in most of the states. These predictable states, however, do not give enough electoral votes to either candidate to determine who will win the overall election, since a majority of the total number of electoral votes cast is necessary for victory.
