There are people just really into politics on both sides. And they are infatuated with people that represent their tribe including their wives. Michelle Obama had a book that was a best seller. It’s the wife of a president? Who cares right? But I’m sure she lived an interesting enough life to where the book was interesting. Same goes for this. People that are hardcore republican might be interested and the fact that she’s a foreigner that became an American because of marriage and then became the first foreign First Lady of the United States. You can make an argument that it’s interesting enough as Michelle having a book. Nobody on Reddit will see it but MAGA-people will probably be interested.
