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.
John Jay
A proponent of strong, centralized government, Jay worked to ratify the United States Constitution in New York in 1788. He was a co-author of "The Federalist Papers" along with Alexander Hamilton and James Madison, and wrote five of the 85 essays. After the establishment of the new federal government, Jay was appointed by President George Washington the first Chief Justice of the United States, serving from 1789 to 1795. The Jay Court experienced a light workload, deciding just four cases over six years. In 1794, while serving as Chief Justice, Jay negotiated the highly controversial Jay Treaty with Britain. Jay received a handful of electoral votes in three of the first four presidential elections, but never undertook a serious bid for the presidency.
