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.
Federalist No. 54
They decided to use population as a determinant of votes in the House of Representatives, but the three fifths compromise that had taken place a year earlier before this paper was the event that sparked controversy between states, men, and political parties. James Madison, Hamilton's major collaborator, later President of the United States and "Father of the Constitution." He wrote 29 of the Federalist Papers, although Madison himself, and many others since then, asserted that he had written more. A known error in Hamilton's list is that he incorrectly ascribed No. 54 to John Jay, when in fact Jay wrote No. 64, has provided some evidence for Madison's suggestion. Nearly all of the statistical studies show that the disputed papers were written by Madison, but as the writers themselves released no complete list.
