United States presidential primary
There is no provision for the role of political parties in the United States Constitution, since the Founding Fathers did not originally intend for American politics to be partisan. In Federalist Papers No. 9 and No. 10, Alexander Hamilton and James Madison, respectively, wrote specifically about the dangers of domestic political factions. Thus in the first two presidential elections, the Electoral College handled the nominations and elections in 1789 and 1792 that selected George Washington. The beginnings of the American two-party system then emerged from Washington's immediate circle of advisors. Hamilton and Madison, who wrote the aforementioned Federalist Papers against political factions, ended up being the core leaders in this partisanship: Hamilton became the leader of Federalist Party while Madison co-helmed the Democratic-Republican Party with Thomas Jefferson.
Anti-Federalist Papers
Considering their number and diversity, it is difficult to summarize the contents of the Anti-Federalist papers. Generally speaking they reflected the sentiments of the anti-Federalists, which Akhil Reed Amar of the Yale Law School generalized as: a localist fear of a powerful central government, a belief in the necessity of direct citizen participation in democracy, and a distrust of wealthy merchants and industrialists. Essays with titles such as "A Dangerous Plan of Benefit Only to The 'Aristocratick Combination and "New Constitution Creates a National Government; Will Not Abate Foreign Influence; Dangers of Civil War And Despotism" fill the collection, and reflect the strong feelings of the authors.
