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. 29
The Articles of Confederation were ratified on March 1, 1781 to be the first constitution of the 13 colonies. Its formation came from the urgent need to stabilize the colonies newly liberated from British administration. It became evident that future prosperity relied on a new structure that gave power back to the general government. At first, people were unsure if this reform would be either beneficial or detrimental to future society. The uncertainty in public opinion had to be answered in order to put the people's trust in the new constitution. Alexander Hamilton, James Madison, and John Jay collectively wrote eighty five essays, known as the Federalist Papers, to persuade people, from those in politics to the average citizen, that the new constitution will be aid in the growth of the young nation. Alexander Hamilton's Federalist 29: "Concerning the Militia", describes what he implies would become of the militia. Historically, militias have been an intricate part in the lives of the people before and after the colonies. Alone, separate militias would have been vastly insufficient in terms of comparability to fighting an army such as the British. However, these battalions do reserve a role in the independence of the colonies.
