Lincoln/Douglas question.

Re: Lincoln/Douglas. The essay doesn’t really tell why Douglas went through with the debates. Cecil gave plenty of Republican reasons, but I don’t know if that’s enough to force an unwilling Douglas to debate. Did he have reasons of his own?

“Douglas agreed to the joint appearances only after Lincoln followed him around the state, making comments from the audience.”
