Why did the federalist favor ratification

They supported the Constitution

Explanation:

The Federalists favored ratification as they were strong supporters of the US Constitution and the system designed by the Constitution.

The federalists believed that changes weren't necessary. They used to argue that the Constitution was definitely great the way it was and nothing needed to change. The Anti-Federalists did accuse the constitution of giving way too much power in the hands of the government, which was not agreed by the Federalists.
