As for President Lindbergh...
-A. Believe in eugenics and nordic superiority, both conventional and respectable ideas that were defended by men like Roosevelt (TR IIRC) and Oliver Wendell Holmes...his hatred for "Yellows" and "browns" was also not unusual for the time, especially the anti-yellow feeling...
-B. Was oddly friendly with the nazis, and had a secret family in Germany...the fact that Ford, Prescott Bush and others were also friendly with the nazis doesn't help
-B2: He was really easy to influence as far as I've heard, and so was turned into being kind of pro-nazi by an acquaintance IIRC...
C. Was an isolationist, Robert Taft Style, anti-Communist...Can't remember much more, was obviously a Republican...
