The FDR paradigm lasted 50 years until Reagan. The Hitler comparison doesn’t make sense in context given that it wasn’t a coalition in the way Bannin describes and didn’t last that long. Whereas the FDR coalition encompassed Northern liberals and Southern conservatives and controlled congress from 1932 to the 1994 mid term elections.
FDR wasn’t the champion of civil rights but he did fix the primary economic problems of the US during the depression. I personally don’t trust Bannon either but he’s clearly comparing to FDR not Hitler.
