Answer:
Because it cannot control the mischief of factions
Step-by-step explanation:
James Madison was against the tenets of democracy. He rather advocated for a republican government. He described democracy as a system where a small number of citizens assemble and administer the government in person. He believed that democracy cannot control the mischiefs of factions because of the localized way in which the government was run. He believed that the government was too close to the people and that democracy struggled for equality which he believed was for the selfish interests of the ruling democrats.
He said that a faction consisted of individuals who were united in some goals that were adverse to the rights of citizens. Too much liberty would fan the flames of faction, and that was what democracy did according to him.
