A wondeful book is Joel Garreau's "The Nine Nations of North America" published in 1980 and not dated at all-- one of his "nations" he called Dixie, which is most of the Confederacy B*U*T also includes southern Ohio, Indiana up to Indianapolis, and "Southernillinois" (all one word) which explains a number of Lincoln's problems (and Oliver P. Morton as well) as well as the places where the 1920's version of the Klan had its greatest influence.
in fact, you can look at Garreau's map of North America, take out the non-US part, and see that each "nation" clearly chose its favored candidate. Anybody else know this book? PETE
