In the evening, Lincoln speaks to Republicans who are celebrating at their headquarters after Chicago's municipal election. Lincoln reflects on his 1858 Senate race loss, and he takes issue with Republicans who, on the grounds of political expediency, voted for Stephen A. Douglas. Lincoln explains the difference between Republicans and Douglas regarding slavery: Republicans believe that slavery is "wrong," while Douglas considers it "simply a question of dollars and cents." Lincoln adds, "[Republicans] are on a ground of unquestionable right," and he encourages them to "Stand by your principles."
