I believe the answer is: his defeat of Stephen Douglas in the 1858 Senate race in Illinois
The defeat happened after the infamous lincoln-douglas debate in the state of illionis, which includes a back and forth debate regarding slavery. Lincoln did not obtain enough supports in the state of illinois, but his view is supported by majority of people in the rest of northern states, which lead to the rise of his popularity during the presidency.
