On  November 8, 1864, Abraham Lincoln was re-elected to a second term as  President of the United States. His running mate was Andrew Johnson,  U.S. Senator from Tennessee. Johnson bitterly and bravely opposed  secession and refused to have anything to do with the Confederacy.  Johnson belonged to the “War Democrats” who remained loyal to the Union.  Although Lincoln was still a member of the Republican party, Johnson  was selected to run with Lincoln on the “Union Party” ticket. 
The  Democratic party nominee was George B. McClellan, the Union general  whom Lincoln fired twice during the Civil War for poor results,  inaction, and disobeying of orders. McClellan and his fellow “Peace Democrats” wanted to end the  war at any cost, even if it meant that the Union would remain  dissolved. 
Going into the 1864 campaign, it wasn’t at all clear  that Lincoln would win re-election. The war effort was going poorly for  the North, with one general after another failing to win victories.  People were horrified by the endless slaughter of soldiers from both  sides. Eventually, the tide shifted in favor of the Union thanks to  Generals Grant and Sherman.
In the end, Lincoln and Johnson won  the election with a comfortable 55%-45% victory in the popular vote and a  landslide in the Electoral College. It must be remembered that the  states which were in the Confederacy did not vote in this election.
