During the American Civil War, the North enjoyed numerous advantages over the South from the start of the conflict onward.

The south had more states and a larger union.
Simply, it could manufacture all manner of war-supplies, including the latest rifle-barrelled artillery, while the agricultural South was increasingly unable to import anything, because of the Unon Naval blockade.

In the US Civil War, the South had a number of advantages. Perhaps one of the best ones was the fact that they did not have to conquer the North to win. Their goal for independence would come when the North no longer wished to continue the conflict.
During the Civil War, the North had very clear advantages over the South. Its naval force had absolute superiority over the Southern navy, which was nearly non-existent. Its industrial production was many times larger and many more times more productive than southern industry. Finally, its population was over twice as large as the population of the South, which would equate to many more soldiers being enlisted and appearing in battle.
No, they had an incompetent President who could not control his cabinet or his Generals. The only advantage was they did not have to face a General Election in 1864.
