The war was clearly about slavery. The Confederate Constitution forbade its states the ability to outlaw slavery, and required them to honor the "property rights" of slaveholders from other CSA states.
Revisionism aside, it wasn't about states' rights, because the CSA denied its own states the right to decide for themselves.
As to why Kentucky declared for the North, I'd imagine it has economic as well as political roots.
