Hmm interesting write up. Taken at face value, it would appear he was a capable bureaucrat (could get things fine within a system), but as a politician he was lacking. Which I guess makes sense.

Politicians have to compromise and made deals with the devil and other things which require good rapport even with those you disagree with. They also need to sell their ideas to people and have them accept those ideas. Bureaucrats on the other hand just have to work well within a system. There are similarities of course, but I think one of them requires more agreeability and charisma than the other where procedure and connections are more important.
