Lincoln’s opponent in the 1864 election was Democrat George B. McClellan, Lincoln’s former head general in the Civil War. Lincoln had fired McClellan as the head general of the Union army and replaced him with General Ambrose Burnside. Lincoln’s 1864 campaign slogan was “don’t swap horses in the middle of the stream.” He trounced McClellan, winning 212 electoral votes to McClellan’s 21.
