How do you think the Indian Removal Act could have passed through
Congress?

By vote

Explanation:

Voting is one of the major forms by which laws are implemented in the Congress, despite how good or bad they are, they would still need to be voted for by the Congress members. Voting gives everyone a voice within the Congress members, so decisions are not taking selectively or in favour of a particular section. The Indian removed act was also passed by voting and was signed into law by President Jackson.
