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
"Federalist No. 10" is generally regarded as the most important of the 85 articles from a philosophical perspective. In it, Madison discusses the means of preventing rule by majority faction and advocates a large, commercial republic. This is complemented by "Federalist No. 14", in which Madison takes the measure of the United States, declares it appropriate for an extended republic, and concludes with a memorable defense of the constitutional and political creativity of the Federal Convention. In "Federalist No. 84", Hamilton makes the case that there is no need to amend the Constitution by adding a Bill of Rights, insisting that the various provisions in the proposed Constitution protecting liberty amount to a "bill of rights". "Federalist No. 78", also written by Hamilton, lays the groundwork for the doctrine of judicial review by federal courts of federal legislation or executive acts. "Federalist No. 70" presents Hamilton's case for a one-man chief executive. In "Federalist No. 39", Madison presents the clearest exposition of what has come to be called "Federalism". In "Federalist No. 51", Madison distills arguments for checks and balances in an essay often quoted for its justification of government as "the greatest of all reflections on human nature."
