FDR, while quiet on prohibition as a politican, was funded by the Busch and Schaeffer families whom he quietly told would be back in business should he be elected. FDR went one step further and regulated beer distribution to the point that micro-brews (like Sam Adams) could not exist legally until Reagan deregulated the industry in 1981.
JFK's campaign was financed with bootleg dollars and without JFK there was no LBJ.
