Why does each representative must live in the state they represent?

Each representative must live in the state they represent to ensure they have a direct connection and understanding of the needs, concerns, and interests of their constituents. This residency requirement fosters accountability, as representatives are more likely to be attuned to local issues and priorities when they share the same community. Additionally, it helps maintain the integrity of the democratic process by ensuring that those in power are part of the population they serve.
