What arguments did james madison and the other federalists use to convince people that the constitution was a good thing

He pointed out that the Articles of Confederation had weaknesses.

The Weaknesses of the Articles of Confederation were:

Each state only had one vote in Congress, regardless of size Congress didn't have the power to tax, or to regulate foreign and interstate commerce There was no executive branch to enforce any acts passed by Congress There was no national court system. Amendments to the Articles of Confederation required a unanimous vote. Laws required a 9/13 majority to pass in Congress

In my honest opinion , i’d say franklin d roosevelt was a president that impacted our nation , i say this because fdr is voted among top three best us presidents and he was the longest serving president by 3 terms , usually presidents only supposed to have two terms increments of 4 years , equivalent to 8 years total before election time. and he established the fdic , through the 1933 banking act and he established the us , social security system , during his presidency, and established a national minimum wage , through the fair labor standards act , fdr led the allied coalition to victory in wwii and he played a major role in the creation of the united nations.
