How is direct democracy in the roman republic different from representative democracy in the US?

Direct democracy in the Roman Republic involved citizens voting directly on laws and policies, particularly in assemblies where they could express their will on specific issues. In contrast, representative democracy in the U.S. relies on elected officials who make decisions on behalf of their constituents, allowing for a more manageable governance structure in a larger and more populous nation. While the Roman system emphasized direct participation, the U.S. model focuses on elected representation to balance interests and manage complexities of modern governance.
