Because they believe power should be with states rather than the government.
Step-by-step explanation:
Anti-Federalists worried that a stronger federal government would be prone to tyranny, and that the new Constitution did not cover enough protections for the rights of individuals and the states. Now although the Anti-Federalists were not able to prevent the ratification, the effects of their efforts are relevant as of today, mostly in existence of the Bill of Rights. The ten changes to the Constitution guarantee many of the rights and freedoms that are now considered the hallmarks of the American Democracy.
