FDR was the one who led America through the Great Depression, even tho it was the actual start of WWII that got us out of it. He also got us through the majority of WWII until he died near the end and the position was taken over by his Vice President, Truman.
Rhode Island lacked a majority for any one faith, so the Rhode Islanders agreed to separate church and state, and believed that mingling church and state corrupted religion.
