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
The Anti-Federalist papers were written over a number of years and by a variety of authors who utilized pen names to remain anonymous, and debates over authorship continue to this day. Unlike the authors of "The Federalist Papers", a group of three men working closely together, the authors of the anti-Federalist papers were not engaged in an organized project. Thus, in contrast to the pro-Constitution advocates, there was no one book or collection of anti-Federalist Papers at the time. The essays were the product of a vast number of authors, working individually rather than as a group. Although there is no canonical list of anti-federalist authors, major authors include Cato (likely George Clinton), Brutus (likely Melancton Smith or Robert Yates or perhaps John Williams), Centinel (Samuel Bryan), and the Federal Farmer (either Melancton Smith, Richard Henry Lee, or Mercy Otis Warren). Works by Patrick Henry and a variety of others are often included as well.
