Why and for the sake of who did Daniel Webster of Massachusetts opposed nullification?

Daniel Webster opposed nullification primarily to preserve the Union and maintain the supremacy of federal law over state law. He believed that allowing states to nullify federal legislation would lead to disunity and threaten the stability of the nation. Webster argued that the Constitution was established by the people, not by individual states, and it was essential to uphold federal authority for the sake of national integrity and the welfare of all citizens. His stance was rooted in a vision of a strong, cohesive nation rather than fragmented states acting independently.
