Rockefeller Republican

The Rockefeller Republicans, otherwise called Liberal Republicans, were members of the Republican Party (GOP) in the 1940s–1970s who held moderate to liberal views on domestic issues, similar to those of Nelson Rockefeller, Governor of New York (1959–1973) and Vice President of the United States (1974–1977). Rockefeller Republicanism has been described as the last phase of the "Eastern Establishment" of the GOP, which had been led by New York governor Thomas E. Dewey. The group's powerful role in the GOP came under heavy attack in 1964 and it lost most of its influence. At a discouraging point in the 1964 primary campaign against Barry Goldwater in California, political operative Stuart Spencer called on Rockefeller to "summon that fabled nexus of money, influence, and condescension known as the Eastern Establishment. 'You are looking at it, buddy,' Rockefeller told Spencer. 'I am all that is left.'"

The term largely fell out of use by the end of the twentieth century, and has been replaced by the term "moderate Republican". Rockefeller Republicans were typically moderate to center-right, vehemently rejected conservatives like Barry Goldwater and his policies, and were often culturally liberal. They espoused government and private investments in environmentalism, healthcare, and higher education as necessities for a better society and economic growth, in the tradition of Rockefeller. In general, Rockefeller Republicans opposed socialism and government ownership. They supported some regulation of business and many New Deal–style social programs. A critical element was their support for labor unions. The building trades, especially, appreciated the heavy spending on infrastructure. In turn, the unions gave these politicians enough support to overcome the anti-union rural element in the Republican Party. As the unions weakened after the 1970s, so too did the need for Republicans to cooperate with them. This transformation played into the hands of the more conservative Republicans, who did not want to collaborate with labor unions in the first place, and now no longer needed to do so to carry statewide elections.
