You may say, "oh that’s all well and good but that was a long time ago what have you done for me lately?"Ingrates!
I think what happened during the Great Depression was that African Americans understood that Republicans championed citizenship and voting rights but they became impatient for economic emancipation.
African Americans languished below white Americans in every measure of economic success and the Depression was especially harsh for those at the lowest rung of poverty.
The Democrats promised equalizing outcomes through unlimited federal assistance while Republicans offered something that seemed less tangible--the promise of equalizing opportunity through free markets.In other words: The Democrats bribed you to forget all your old friends. No mention of Republican racial politics from the Compromise of 1877 to Nixon's Southern Strategy, nor of the traditional conservative attitude toward integration and equal rights, nor Jesse Helms, nor Strom Thurmond, et alia and ad nauseam. The Civil Rights Act Paul only mentioned defensively, as something from which he'd "never wavered" except for that part about using the power of the state to enforce it.
Layer in a generous helping of self-pity ("and when I think of how political enemies often twist and distort my positions... My hope is that you will hear me out, that you will see me for who I am, not the caricature sometimes presented by political opponents... Republicans are often miscast as uncaring or condemning...") and you've got a perfect speech -- not for the folks at Howard University, but for the commenters at Reason who seem to understand Paul perfectly ("Maybe Paul should have offered up more free shit since that seems to work so well").
So in that sense it was a great success.
