WI: FDR dies of Influenza in 1918?

Wikipedia said:
In the summer of 1918, Roosevelt traveled to Europe to inspect naval installations and meet with French and British officials. In September, he returned to the United States on board the USS Leviathan, a large troop carrier. On the 11-day voyage, the pandemic influenza virus struck and killed many on board. Roosevelt became very ill with influenza and a complicating pneumonia, but he recovered by the time the ship landed in New York.
Franklin Delano Roosevelt looms large over American history. Having overseen America's recovery from the Great Depression and leading the country to victory in World War Two, FDR forever left his mark on not only America but the whole world. However, his presence in history begs the question, what happens if he wasn't there? What happens if FDR died in 1918 of influenza on the USS Leviathan, butterflying his presidency? Who replaces him as the Democratic nominee in 1932? Who leads America during it's recovery from the Great Depression? And who transforms America into a world power as a key member of the Allies during WW2?
