FDR's social welfare programs benefited people of all races. So your explanation does little to explain why blacks are ~90% Democratic today.
Well, no actually is was deleterious to all Americans. ANd FDR refused to push anti lynching legislation because he didnt want to offend Southern Dems.
But I answered your queston already: Dems figured out dishing out gov't cheese to blacks was the way to buy their vote.
(My bold)
Ugly in so many ways!
But let's cut to the chase: When can all those prospective Black GOP party members expect to see a Black GOP presidential candidate with an actual possibility of winning the GOP presidential nomination?
Does the Food Stamp program actually go back to FDR? Good for him, if so. Of course, the main point of that effort was to prop up farm prices, to save farmers & their crops - it was originally called the Food Commodities Program, as I recall. Fed gov was a middleman, buying crops @ a base price, processing, canning & then distributing goods on a sliding income scale? (That may have come later - @ first, I believe it was to help families keep body & soul together. I don't recall what the first distribution criteria were.)
We've already seen a black GOP candidate. He was harassed to death and called all sorts of things by the open minded liberal white establishment.
The real question is, When can Democrats field a successful black candidate?
