The states believed in following the constitution literally, which was possible in the early days.

Explanation:

Black people in the state of New Jersey along with women could vote as long as they met this criteria:

who were over the age of majority,

had more than fifty pounds of wealth

had lived in New Jersey for more than six months.

The black people  had to be free persons of the state to vote however, essentially not slaves.

This was possible because some idealists followed the word of the constitution literally and wanted equality for all.

This law was later repealed by the states by politicians who lobbied against it.
