I'd put one more advantage to the Union: they had VASTLY better industrial capacity. The Union states could way out-produce the Confederate states when it came to armaments, and the the Union's amazing United States Military Railroad meant the Union could move a lot more troops, arms and other supplies to the front lines faster than the Confederates could.

The Confederacy had internal railroads that they could have utilized to an advantage early in the war. The only time the South used them was at Chicamauga when Longstreet's Corps was sent from Virginia to Georgia. The Confederates had a tactical advantage that was not used. They could have used the railroads to move troops and overwhelm the Federal sluggish armies and obtained their objective.
