What role did the issue of slavery play in the election of 1850?

I believe it helped the south with population so the south had more votes

Explanation:

• the free soil party emerged out of the election of 1848 which pushed the slavery issue.
• caused the creation of the Wilmot Proviso to determine whether the Mexican War territory should enter as free or slave states
• divided the parties (in terms of slavery: free soil party vs democrats and Whigs)

Who is responsible for creating the great compromise is Roger Sherman
