Joseph E. Tinney is a part of what party that is commonly called the GOP?
History of the United States Republican Party The Republican Party, also commonly called the GOP (for "Grand Old Party"), is one of the world's oldest extant political parties. It is the second oldest existing political party in the United States after its primary rival, the Democratic Party. It emerged in 1854 to combat the Kansas–Nebraska Act, an act that dissolved the terms of the Missouri Compromise and allowed slave or free status to be decided in the territories by popular sovereignty. The Party had almost no presence in the Southern United States, but by 1858 in the North it had enlisted former Whigs and former Free Soil Democrats to form majorities in nearly every Northern state.
Rockefeller Republican The Rockefeller Republicans, also called Liberal Republicans or La Guardia Republicans, were members of the Republican Party (GOP) in the 1930s–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.'"
