Abraham Lincoln won re-election in the 1864 presidential election, receiving 55% of the popular vote. The two major candidates were Abraham Lincoln for the Republican Party and George B. McClellan for the Democratic Party. The Republican Party aimed to continue the Civil War and abolish slavery, while the Democratic Party sought to end the war and preserve the union without interfering with states' rights regarding slavery. Lincoln's victory established that the Union would continue fighting until the Confederacy surrendered and slavery was abolished throughout the nation.
