Answer:
The electoral college is the body that actually elects the U.S. President. The United States is a federal republic, and citizens elect the president indirectly.
Step-by-step explanation:
Each state grants a number of electors proportional to the population of the state on the basis of winner-takes-all, that is to say, the candidate who wins the plurality of votes in a state, takes all the electors from that state. Only two states have a somewhat different mechanism: Nebraska and Maine.
Electors from each state meet and form the electoral college. The candidate who wins the most electoral votes takes the presidency.
The elections of Andrew Jackson in 1824, and of Donald Trump in 2016, are two examples of presidents who won the electoral college despite not winning the popular vote.
