Step-by-step explanation:
James Madison referred to what we now often call an interest group as a "faction". In Federalist No. 10, he discusses the concept of factions as groups of individuals, either in the majority or minority, who are united by a common interest or passion that may be adverse to the rights of others or to the overall welfare of the community. Madison saw factions as a natural part of social life and cautioned that while they could be a source of mischief, it was essential to allow them to exist and compete against one another in order to protect individual freedoms and prevent tyranny.
While interest groups often support or oppose political candidates, their primary focus tends to be specific issues, such as environmental protection, gun rights, or professional concerns. Unlike political parties, which seek broad coalitions to elect candidates, interest groups can be highly specialized and sometimes politically influential due to their focused nature.
