How did the candidates' opinions reflect the
slavery debate in the United States?
•I couldn’t find the answer so I liked one and it was right so the ANSWER IS A

Their opinions reflected the divide on slavery in the North and the South.

Explanation:

I believe the question is related to the "Lincoln-Douglas" debates whereby Lincoln believed that slavery will prevent the whole nation to be unified. On the contrary, Douglas stated that slavery should depend on the people whether they find it lawful or unlawful. This was called the "Freeport Doctrine," which antagonized the white people in the Southern area. Such opinions showed how slavery was divided in the North and the South.

So, this explains the answer.
