Lincolns election opponent in the election of 1864?

Lincoln was elected as the 16th President of the United States, beating Democrat Stephen A. Douglas, John C. Breckinridge of the Southern Democrats, and John Bell of the new Constitutional Union Party. He was the first Republican president, winning entirely on the strength of his support in the North: he was not even on the ballot in nine states in the South, and won only 2 of 996 counties in the other Southern states. Lincoln gained 1,865,908 votes (39.9% of the total), for 180 electoral votes; Douglas, 1,380,202 (29.5%) for 12 electoral votes; Breckenridge, 848,019 (18.1%) for 72 electoral votes; and Bell, 590,901 (12.5%) for 39 electoral votes. There were fusion tickets in some states, but even if his opponents had combined in every state, Lincoln had a majority vote in all but two of the states in which he won the electoral votes and would still have won the electoral college and the election.
