I found Yes, Minister on PBS. I had been involved in student politics at university and later in local, provincial and federal politics. As I watched Yes Minister and then Yes Prime Minister, I instantly recognized the powerdrunk paranoid world of real politics.
A sitcom, the characters were so true to reality that I knew them, at once. Politicians worried more about what was said in the daily paper than in politics. Officals who built up power and turf over decades. Civil servants who changed the definitions of work and merit.
The series takes place before the Internet and 24 hour coverage turned politics into a theatre of the absurd. Watching this provides not only laughs but a primer on electoral politics which you can use to this day.
