Who opposed the new constitution, fearing it would intrude on states' rights?

• A. Antifederalists
• B. Federalists
• C. Republicans
• D. Progressives

Answer: (A)

The main idea being tested is the tension between national power and state sovereignty in the ratification debate. The new Constitution would create a stronger central government than the Articles of Confederation, which led some people to worry that states would lose authority and that individual rights might not be adequately protected. Those who opposed the Constitution—Antifederalists—argued that such a shift would intrude on states’ rights and authority. They pushed for protections like a Bill of Rights to constrain the federal government and safeguard state prerogatives. The Federalists, in contrast, supported ratification and argued for a balanced, strong enough central government with checks and protections, while the other labels you mentioned aren’t aligned with this particular concern about state power during the ratification period.
