They are really thorough and exhaustive! Here is a glossary of every single person of influence in magical Britain and how well he knows them and which projects he could trust them on and avenues to reduce or increase their influence or his influence over them, updated after regular holiday parties and with notes about frequency of personal correspondence (he is talking to everybody, all the time). There are forty pages on Ministerial reorganization. There are three full notebooks on the Statute and the international conference that would need to be held to overturn it and the people he is in the process of persuading to hold that conference and proposed timelines and their drawbacks. There are eight pages devoted to prospects for marriage and their political advantages and disadvantages.
And then there are plans for once the Statute is repealed and he is Minister of Magic: infrastructure, research, governance, Muggle-magic relations, goblin relations, centaur relations, werewolf regulations, merpeople regulations, international conventions for dragon handling, potential things to do about the human slave trade, potential things to do about the Muggle colonial holdings in Africa -
