In an extensive republic however, each representative would be chosen by a greater number of people and there would be more candidates to choose from than in a small republic, therefore it's more likely that a worthy and uncorrupted candidate would be chosen as representative in an extensive republic. .
A major concern of the Anti-Federalists that was the foundation of their demand for a small republic was the fact that they believed a small republic would guarantee that the voices and opinions of all the people would be heard. The Federalists completely disagreed and explained that in actuality if a person were to have a differing opinion in a small republic, that person would be confronted by a massive majority sharing the same opinion, and the individual would not be heard at all. In a large republic however, where various opinions exist, a domineering majority would never be able to form and therefore, unpopular views would be heard and the minority would be protected. Additionally, a menagerie of wide-ranging opinions in a large republic would result in the government making much more moderate decisions for the public good as opposed to extreme and biased decisions. .
Madison described how within these majorities and minorities, existed factions, groups of people united by a common interest that was counter to the public good. Acknowledging that people are factious by nature and will inevitably disagree when it comes to their interests in almost every matter, the only way to prevent against the oppression of minorities by majority factions, while still protecting civil liberties, was through a strong national government. Realistically, Madison explained, factions will exist within the government as well, because there must be some element of interest in order for judges to make decisions, therefore once again a strong national government is needed to control the effects of factions even within the government.
