But what's been said about 32 is true. The New Deal is what won Blacks over to the Democrats, not the Depression itself
True. But that kind of goes without saying. If FDR hadn't offered a solution to the problems caused by the depression, there would have been no point in switching to the Dems.
If other people hadn't switched earlier, though, there wouldn't have been no FDR. I obviously meant no point of switching for blacks, who were firmly rooted in the Republican coalition and had good reasons not to trust Democrats.
The way it happened makes sense, but that doesn't mean the alternative would be unthinkable either.
