Why were federalist leaders not satisfied with having gotten only nine states to ratify the constitution?

-all 13 states were required to ratify the constitution for it to go into effect.
-without more state support, the federalists would lose power to the anti-federalists.
-the constitution included the bill of rights, which threatened the power of the central government.
-the country would be fragmented if new york and virginia didn’t ratify the constitution.
