Exactly, go to page 15 of this study of historical ideologies of states (based on the policies of state government)

Vermont used to be centrist/slightly right-leaning in the 1930's and was probably more conservative in the Early 20th century, and much to the chagrin of Oldies types, the Deep South was always deeply conservative in its governmental policies, even back in the 1930's during the periods of full Democratic control.
These charts should counter many historical revisionist stances.
What would you say was so conservative about these deep Southern states? I absolutely refuse the disturbing revisionist assumption that being racist/favoring segregation = conservative.
According t many on the left, anything that is bad is automatically right-wing. There have been people who have said that Stalin was right-wing.
