Partisanship and Politics
The form of government (council manager) that I have operated under and within, generally speaking, for my professional life - is by far the most professional, productive and efficient form of governance structure in the US local government sector. You blend the elected official expertise in policy and strategic thinking and civic responsiveness to issues the community desires, with the seasoned, educated touch of a professional, ethical and trained non-partisan administrator.
This is the composer - conductor relationship.
