The electoral college consists of 538 electors who are distributed throughout the states. The amount of electors that an American state has depends on the state's population. A larger population has more electors to represent the state, whereas a state with a smaller population has less electors.
In the past, many people were fairly politically uninformed. Due to this, the electoral college was established to represent the general public, and the electors were required to make the most beneficial presidential decision for their state. The electoral college continues to represent the American public in presidential elections today. The electors often vote based on their state's citizens' presidential preference. However, sometimes the electors strongly believe in a different candidate and cast their votes towards him/her. The official purpose of the electoral college is to represent their state in presidential elections, which determines the President of the United States and the Vice President.
The Electoral college consists of 538 electors - each state having a different amount of electors. They determine the winner of the presidential election - both the President and the Vice President.
