The Iron Triangle...what is it? Why is it critical for the functioning of a Republic???Who are the "players" involved?

The Iron Triangle is the relationship between the legislature (Congress), Bureaucracy, and nterest groups. The agencies go to the interest groups that correspond with the same political rule as the branch of government is in charge of. The bureaucracy does not rely on the general population however, because the population is somewhat disinterested and uninvolved. Interest groups provide support for the Congress either in money or votes, while Congress gives more attention to that particular group. Congress then offers funding for those groups that they support though the agencies. This system ensures that all three systems are satisfied, by having them work codependently in achieving that satisfaction. The Iron Triangle protects the government from corruption from outside influences, since only the Congress, agencies, and interest groups are involved.
