Okay so "bread and butter" issues are something that affects everyday people. For an example, road conditions. Issues that have some connection to money in some way are normally described this way. Mostly by journalists. For the Civil War, the Union soldiers were fighting to preserve the Union and to fight to end slavery. They wished to free all people of color from control in the South. Italians, African Americans, you named it they were trying to help give them freedom. They were fighting for freedom, patriotism, and to defend their home. There were several other reasons besides slavery. Population, economics, and manufacturing are examples of others. Hope this helps!
