B. On one hand, the Southern Democrats were focused on and pushed for war. To them, a successful conquest meant that they would own more slave-territory hence preventing the North (which was growing faster than they were) from outnumbering them.
The North, on the other hand, speculated that the result of a successful conquest would substantially increase slave power. They wanted a more industrialized but not by increasing the existing geographical entity. After the conquest, David Wilmot, Democratic Congressman, introduced the Proviso, which aimed to dampen the practice of slavery in new territory acquired from Mexico. Wilmot’s proposal (which became known as the Wilmot Proviso) failed to gain popularity with the Congress, rather it created more loggerheads between them.
