Why did the delegates at the philadelphia convention turn down the idea of including a list of citizens' rights in the constitution? they believed that such a list would limit economic development. they believed that since the federal government was already limited to its expressed powers, further protection of citizens was not needed. they believed that protecting citizens' rights was not an important responsibility for government. they believed that citizens should vote directly on which rights should be protected. they believed that such a list would make government too weak to protect national security?
