What is the primary difference between jefferson’s and madison’s beliefs about the bill of rights?

The primary difference between Jefferson's and Madison's beliefs about the Bill of Rights is that:

Madison disagreed with Jefferson's belief that a bill of rights would protect citizens.

Explanation:

According to Thomas Jefferson in his letter to Madison, he said "A bill of rights is what the people are entitled to, against every government on earth." This simply means that, he believed that every American should be protected from the infringement of liberties from Government. Liberties such as: religion, speech, press and petition.

However, James Madison disagreed with him, and as a federalist, he believes that, the constitution has already limit the power of the federal government, thereby bill of right is unnecessary at that point.

the correct answer is: the fact that the anti-federalist papers were considered poorly written.
