But for the most part, Southern whites did not reciprocate this interest. Southern Democrats in Congress were the quickest to support military action in Europe. As early as 1939, public opinion polls found that support for the Allies – including the possibility of U.S. military action – was strongest among Southern respondents. Southern newspapers, too, opposed the Nazis and rejected comparisons between the German regime and their own region’s racial politics.

Nearly all white Southerners could trace their heritage to the United Kingdom, and evangelical Protestantism has long been an important component of Southern culture. Perhaps it is not surprising, then, that Southern whites were not particularly drawn to a regime that was anti-British and anti-religion.

Although Southern newspapers sometimes compared Nazi atrocities to the Ku Klux Klan, the Southern KKK itself was generally not pro-Nazi – at least not then. After the war, the Army sent Congress a list of 1,000 Nazi Party members living in the United States. Only about 2 percent lived in the Southern states.

I can't actually find those polls or data. What about others? I wonder what these people would think if they saw the current state of the nation......
