As leader of the Republican Party, Lincoln was outspoken in his views on slavery and expressed them during the debates of 1858. Which of the following would best fit with his position?
A. Compromise of 1850
B. Dred Scott decision
C. Kansas-Nebraska Act
D. Wilmot Proviso

D. Wilmot Proviso

Explanation:

Lincoln was supporting Wilmot Proviso, which was a failed attempt to ban slavery. When Abraham Lincoln and Stephen A. Douglas met in a series of seven debates as they ran for Illinois Senate seat, they heatedly debated a critical issue that day, slavery. Debates raised Lincoln's profile, helping to encourage him to run for president two years later. However, Douglas will actually win the 1858 Senate election.
