The RNC is the Republican National Committee – or, put another way, the entire construct of the professional Republican Establishment and those who derive benefit/affiliation from the entity therein, the business end. (National, State and regional political entities; polling consultants, campaign consultants, committee employees, etc). The RNC gets the politician elected to Washington DC. The GOP, or GOP(e), is the financial class or group of financiers who pay the RNC and derive benefit from the policy creation within Washington DC. Wall Street banks and banking interests, the U.S. Chamber of Commerce, K-Street Lobbyists, etc. are all part of the machine that tells the politicians what to do.
