why does brutus believe that a republic as large as america would be a problem?

Brutus believes that a republic as large as America would be a problem because it would be unable to sustain a truly democratic government. He argues that citizens in such a large republic would be too far removed from their representatives, leading to a lack of accountability and making it easier for an elite ruling class to dominate. This distance would cause representatives to be less familiar with their constituents' interests, which threatens the principles of a free republic. Additionally, Brutus fears that a large consolidated government with extensive powers would undermine the sovereignty of states and could lead to tyranny by concentrating too much power in the national government. He also worries that the necessary and proper clause and supremacy clause in the Constitution give the federal government uncontrollable power over states, essentially nullifying state authority, and that this centralization would erode personal liberties. In essence, Brutus advocates for a confederation of small republics, which he believes would allow citizens more direct influence over their leaders and laws, preserving liberty more effectively than a large national government could.
