Who is Franni Franken from the nonfiction book, Al Franken, Giant of the Senate?

Though Franken keeps much of his personal life private, he makes his wife Franni's presence known at every step of the journey as an essential component to his success. From her humble beginnings, to her constant support, and her ability to be a level-headed voice of reason, Franni is one of Franken's most consistent and relied upon tools. He even credits her with saving his first Senate campaign with a heartfelt and courageously honest advertisement that impacted many voters right before the election. Franken and his wife have two children together, daughter Thomasin and son Joe.
