If you have Paramount+, don’t mind doing a free trial, or like to sail the seven seas, you can watch The Reagans documentary series. Another documentary that gives you some insight into the type of people they were is the Rock Hudson one. The TL;DR on that one is that they had been good friends for decades, especially Nancy, and the moment it came out that he had AIDS, they pretended he had never existed.

Ronald was basically an idiot but Nancy was a truly foul human being.
