written by Hamilton, explains the system of electoral college to elect a president.

In the electoral college system, each state would choose a number of electors equal to the state's number of senators and representatives in the government. These electors would gather and cast votes that would decide the president.

The vice president would also be chosen by the elector college and would be the nominee who received the second-highest amount of votes.

Hamilton argues that in the electoral college system, \"the sense of the people\" will play a key role in selecting the president, while, at the same time, affording \"as little opportunity as possible to tumult and disorder.\"

An energetic and forceful president is essential to good government. National defense, sound administration of the law, and the protection of property rights all depend upon the vitality of the Presidency. In addition, an energetic president best protects liberty when faction, anarchy, and the excessive ambitions of others threaten it.

It is best to have only one president in charge of the executive branch to ensure unity, strong authority, and some secrecy

It helps defend against foreign attacks, consistent administration of laws, protects property against injustice, and secures liberty from ambition, faction, and anarchy.
