Both scientific art and artistic science.
Art is a human science which is developed by them genetically and by practicing it.
Art is a way for one to express themselves, it can be educational at some points,like if it was a poem explaining something. Art can have to do with since,like a project that had to do with something...
Some parts of political science may be considered an art, such as political philosophy, but, overall, it is mostly a science.
It is a Science, not is a form of representing something. While Politics is the Science it's the study of leadership and how it affects people.
