Federalists.
The Federalist Papers
Delaware had the highest percentage of people vote in favor of ratifying the Constitution. In December 1787, Delaware became the first state to ratify the Constitution, with a vote of 30 to 0 in favor, reflecting unanimous support among its delegates. This strong endorsement demonstrated Delaware's commitment to the new federal framework.
New Hampshire
By ratifying the US Constitution.
Each state held its own ratifying convention
The framers were able to bypass congress and state legislature in the process of ratifying the new constitution because there are two methods of ratifying and they choose the one that bypasses congress. All they had to do is have the people vote on ratification and get a majority vote.
The Constitutional Convention designated the states ratify the new Constitution by conventions elected specifically for the sole purpose of ratifying it.
The first 13 states ratified the Constitution. As new states were added, they had to agree to be a part of the Constitution but did not ratify it.
The Anti-Federalists did not like the new strength the central government would possess. Additionally, the constitution did not have a Bill of Rights when the states were in the ratifying process.
They would not have enough state votes to pass the constitution if slavery was outlawed by it. The south would have voted against it.
The Federalist Papers.
The reason Federalists were anxious and concerned about New York and Virginia ratifying the proposed US Constitution was because these were important States and without their support, the ratification of the new constitution was in doubt.
