Answer:
2. to affirm his belief in popular sovereignty.
Explanation:
In these lines, Abraham Lincoln affirms his belief in popular sovereignty. He states that the states should have the right to order and control their own domestic institutions in the way that they see fit. Moreover, he argues that this is essential to the balance of power in the country. This is because Lincoln believes in popular sovereignty, and he thinks that ultimately, the people should be the ones to make their own decisions.
