I've got a few recommendations regarding presidents.

Gimsons Presidents: Brief Lives from Washington to Trump - Each President get a few pages, and whilst it's not as 'hard hitting as some of this list, it does have some very fun writing, and really nice art as well.

The Presidents by C-SPAN - They take the most recent C-SPAN Presidential poll and dedicate time to each president based on their ranking. A lot of it is transcribed from audio interviews, but it's still a solid read if you're looking to get a grip on these guys.

The Presidents: 250 Years of American Leadership (By Ian Dale) Another round up, but this is perhaps more..... current than the C-SPAN book as it takes newly created essays written exclusively for this book.

The Complete Book of US Presidents - More of an encyclopaedia than anything. It's massive, but it covers everything from First Lady's to Inaugural speaches.

Could probably find a few more if you're interested?

Check out Blackshirts and Reds, by Michael Parenti. It's an amazing book about the history of the relationship/battle between fascism and communism in the world over the 20th century (spoiler alert, fascism won).

October by China Miéville is a great telling of the Russian revolution.
