Those who believe the federal government's powers should be narrowly interpreted are known as Anti-Federalists. They advocated for a weak national government and strong state governments, fearing the possibility of tyranny and advocated for the addition of a bill of rights to the Constitution.
Step-by-step explanation:
Those who believe the federal government's powers should be narrowly interpreted are known as Anti-Federalists. The Anti-Federalists were advocates for a weaker national government, fearing that a stronger federal government could lead to tyranny and the erosion of individual and state's rights. They pushed for a bill of rights to protect citizens against potential government overreach, arguing that provisions like the elastic clause in the Constitution could allow the federal government to extend its powers beyond what was intended by the authors of the Constitution. Their perspective reinforces the principle of federalism, which posits that the federal government should only exercise the powers specifically delegated to it by the states or the people.
