Here's one to chew on. The Republican Party as a national party is a member of an international political organization... a New World Order type super political party. The other parties involved is similar international super-parties are the Green Party, the Democratic Socialists of America, the World Socialist Party of the United States, the United States Pirate Party (Hackers/Data Pirates), and Black Bridge International (Anarchists). The GoP is sure following an interesting model here.

Oddly, the Democratic Party (the one accused of being too global) is not a member of such an international organization. Specific sub-blocks within the Democratic Party are, such as the New Democrat Coalition and the Progressive Policy Institute.
