Who were the two main candidates in the 1864 presidential election?

The 1864 presidential election featured Abraham Lincoln running for re-election against George B. McClellan, who was the Democratic candidate. Lincoln, representing the Republican Party, was seeking to continue his policies during the Civil War, particularly focusing on the preservation of the Union and the abolition of slavery. McClellan, a former Union general, had a more conciliatory approach to the South and was critical of Lincoln's handling of the war. This election was significant as it took place during a tumultuous period in American history, most notably during the Civil War. Lincoln's victory signified a continued commitment to the war effort and the policies that would lead to a reunified nation. The election is a crucial point in understanding the political landscape of the era and the differing ideologies concerning the war and Reconstruction that arose during this time.
