Why were political parties viewed as so dangerous by the founding fathers?

the framer believed that political parties were factions. a faction is usually a dissatisfied group formed within a larger group. the framers thought that factions might fight to promote the interest of their own members. they feared that the strongest faction would control the government. in such a case, government would not protect equal rights and interests of all the people. instead the government would promote the interests of the party in power.
