Although I did get into some local voting a lot of years ago I was meaning the black vote for president, in 1936 the blacks did a complete reverse from Republican to Democrat.
In 1932 FDR won the typical Dem portion of the black vote with 23%, in 1936 that historical voting pattern permanently reversed with 71% of the black vote going for FDR and they never looked back.
Black party registration lagged some but it caught up quickly enough.
Interestingly LBJ got a record (before Obama) 94% of the black vote, before the legislation he was talking about.
LBJ got sucker punched in an election in Texas. Fell victim of the “look, we found more votes” . Johnson knew he had been screwed and let it slide. He let it slide until the next election when he used the “found votes” tactics himself to cement his victory..
Crooked elections, interference from the FBI, nothing new , it should be no surprise they are screwing Trump now.
I know what you were saying, you and I have discussed this before, I believe. Mainly because so many Northern Blacks were enfranchised saw such a dramatic turn with FDR’s reelection. Southern Blacks, even those that could not vote, took another 3 decades to catch up with their Northern brethren on leaving the GOP. Had they been fully enfranchised in both regions, it’s quite possible the South alone could’ve kept the overall Black vote majority GOP for President until 1964.
Alas, it was the massive polarization with Goldwater, who ironically WAS pro-Civil Rights, but against the CRA because it was too much a government-mandated overreach, and not helped by MLK, Jr. denouncing him as a “tool of Southern racists” (which, of course, he wasn’t). Even with Nixon, who got 1/3rd of the (not yet fully enfranchised) Black vote in 1960, he struggled to get over 10% or so just 12 years later (and despite the prominent support of Sammy Davis, Jr), the number the GOP has been stuck at for 60 straight years since. Even more remarkable the Black vote going for the racist candidate Carter in 1976, just 6 short years after he ran an openly race-baiting campaign for Governor (with Ford still only getting somewhere around 15% of the Black vote, which I believe was either tied with or slightly better than Trump’s performance in 2020), showing just how thoroughly radicalized and polarized the Black vote was, and sadly still is today.
