The key reason most anti-Federalists shifted to supporting the Constitution was because they were promised a bill of rights. This promise addressed their concerns about protecting individual liberties and rights from potential government overreach. The addition of the Bill of Rights, the first ten amendments to the Constitution, reassured many anti-Federalists that their essential freedoms would be safeguarded.
Additionally, the promise of term limits on the office of the president was not a significant factor in swaying anti-Federalists to support the Constitution. The issue of term limits was not a prominent part of the debate during that time.
While good relations with Native Americans were important in the early days of the United States, it was not a primary factor that influenced anti-Federalists to change their stance on the Constitution.
Likewise, the presence of a bicameral legislature, which is a two-chamber system of government like the Senate and the House of Representatives, was already part of the proposed Constitution and was not a specific promise made to anti-Federalists to win their support.
