These are the opinions of some individuals on the annexation of a new territory to the United States in the early 1840s. Speaker A: The acquisition of this territory will improve the southern economy and expand cotton production in the United States. There is no reason to avoid it!
Speaker B: Annexing this land will lead to sectional divisions and further arguments about whether slavery should be allowed. While we would gain a state, we’d also gain more problems.
Speaker C: To see the cotton industry expand into this new state would mean also watching the evil of slavery expand. All abolitionists must be against it!
Speaker D: Not only does adding this new territory upset the balance of power between slave and free states, it adds an immense amount of land and population to the South. The North would never again have the upper hand.
