Thinking about it, there's a lot in common between the skillsets needed to be competent presidents and lawyers. Both need to be convincing, make a case to an audience, and understand the law.
About the only things I can think of that presidents need to do that has nothing to do with being a lawyer are being the head of the military and making decisions around military operations.
Personally, the game I run the most is Shadowrun. Managed to transition my DnD group to Pathfinder 2e and it's great. Pathfinder is DnD but so much better.
