I want to know the answer to the following question:
What political group has a disproportionately large number of Protestants?
All the background I'm provided with is that "Numbers of the most wealthy and affluent American families as the Vanderbilts and the Astors, Rockefeller, Du Pont, Roosevelt, Forbes, Whitneys, the Morgans and Harrimans are Mainline Protestant families.". Is that enough to answer the question?
