Why are some presidents elected by an electoral college

Presidential elections use the 'Electoral College' to elect some presidents instead of allowing people or Congress to elect the president directly because the founding fathers of electoral college was afraid of direct election for electing the president. Hence, Some presidents are elected by an electoral college.

Explanation:

The electoral college is defined as a process where the founding fathers established 'electoral college' in the constitution as a compromise between electing the 'president' by a 'popular vote of qualified citizen'and electing the 'president' by a 'vote in congress'. A majority of 'electoral votes' is needed to elect president. Each candidate in a state who is running for president own a 'crew of electors' known as slate. Thees slate are normally chosen by the candidates of political party in a state but 'state laws' differ on how the 'electors' are selected.
