First, I'm not really sure where you get the idea that Wilentz (or McPherson, for that matter) is my "favorite Lincoln author." I've never said that. I don't know that I have a favorite.
I got the idea because you wrote on your Post #27: "When Sean Wilentz, a historian that I deeply admire, raised his voice in protest about the 1619 project, that got my attention, because I think Wilentz is one of the greatest historians working."
"So very difficult a matter is it to trace and find out the truth of anything by history." -- Plutarch
