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.
The Federalist Papers
However, Hamilton's opposition to a Bill of Rights was far from universal. Robert Yates, writing under the pseudonym "Brutus", articulated this view point in the so-called Anti-Federalist No. 84, asserting that a government unrestrained by such a bill could easily devolve into tyranny. References in "The Federalist" and in the ratification debates warn of demagogues of the variety who through divisive appeals would aim at tyranny. "The Federalist" begins and ends with this issue. In the final paper Hamilton offers "a lesson of moderation to all sincere lovers of the Union, and ought to put them on their guard against hazarding anarchy, civil war, a perpetual alienation of the States from each other, and perhaps the military despotism of a successful demagogue". The matter was further clarified by the Ninth Amendment.
