I've always been a fan of the 19th century novel, of the novel that is plotted, character-driven, and where the passage of time is almost as central to the novel as a major minor character, the passage of time and its effect on the characters in the story.
I remember a big meeting with the hosiery trade in Harold's ministerial room.
I think Karl Rove saw that in George W. Bush early on and understood the impact that he could have on Texas politics and probably on national politics.
