@077e1dff Yes, he's maybe the premier example, isn't he? Then, too, there are the folks in the KKK whose second coming in te 1920s was especially strong in places like Indiana, and whose strength was in churches. In my hometown of Little Rock, big ads for KKK rallies as the Klan reformed in the 1920s were signed by lists of local pastors who spoke at KKK rallies and urged people to join the Klan to save the (white) nation.

The KKK were all over. For a short period of time, as a college student,  I lived in a house Menomonie Wis. The home had belonged to a state senator. In the attic I found a stack of KKK newsletters. Pretty bizarre, I gave them to the history dept of the University. Northern Wisconsin is still a Republican area. 

 @077e1dff Yes, they were all over. They were also especially concentrated in Indiana in what historian Linda Gordon calls the "second coming" of the KKK.
