In the 1864 U.S. presidential election, the Democrats nominated Union Army General George McClellan for U.S. President and Ohio U.S. Representative George Pendleton (who later became notable for the Pendleton Act) for U.S. Vice President. During the campaign, McClellan vowed to do a better job of prosecuting the Union Army effort in the American Civil War than incumbent U.S. President Abraham Lincoln did. Ultimately, the McClellan-Pendleton ticket lost to the National Union ticket of Abraham Lincoln and former U.S. Senator Andrew Johnson.
