Politicians often get or take a lot of credit for things done by many people by the nature of how we view things and of our political system. Conversely, they also get the flack for a lot of things, whether fairly or not because it might have been the errors or poor performance of many others. As the symbolic focal point for a lot of things, that’s how accountability is thrust upon them.
For their sake of accountability, the ability to be able to decide how much or little to get involved is a key trait to a good politician because nobody is an expert at everything. In fact, the more important politicians trusted with responsibility for various portfolios might not even know much about the issue. Their selection of responsibility might be for any number of reasons, from political like having power distributed in an area, to the lack of anyone else suitable, whether by knowledge or decision-making ability.
