Anti- Federalists feared the Constitution would give the U.S. Government too much power and little power to the people, which could lead to tyranny. Anti-Federalists focused more on the idea of the states/people having more rights or authority than the U.S. Government. Federalists insisted the government should have more power/authority. Federalists believed the U.S Constitution would be successful and not lead to the huge debacle that was the Articles of Confederation (A prime example of the States having too much power)
