if you are talking about the inner workings of government like the civil servants then from my experience the best bosses have been ESTJ by far. They are typically fair and get the job done quickly. Not only that but all of my ESTJ bosses do things proactively.
Are any of you actually civil servants? Working for certain types isn't fun. ENTP for example = BAD BOSS. They micromanage and their divisions fall apart. ENTJ not that bad really. They can be pushy but fair. They like to see things get done and can be good motivators. INFP? I love you guys but no. For one they hate the confined cubicle setting and they are too subdued. I can't speak of SF at all. INTP no way. They don't have as much problem speaking their mind as INFP but sometimes you can't understand what they are trying to say. I know one ENFJ boss and she is ok, can't really say anything negative really. Notice I never said myself? We get shit done but we don't like to finish.
If this is about political leaders then everything I just said goes out the window. Government leaders in the inner workings, sorry all you ESTJ haters but they are king and for good reason.
