the high probability that if you asked most Trump voters to name a dozen past US presidents, they probably wouldn't be able to!
Nothing like starting a discussion with an insult. What could possibly go wrong? 
He’s doing everything he said he would!
Like that’s a good thing... 
You didn't even need to tell us that you have a very smooth tone, and that you're "the most historically rooted person in the group". It's very obvious. You did great! And it's not just me that says that. This guy does too.........and,yeah, it's Hercules
Oh yeah there were -
1964 Presidential election -
What tipped the GOP numbers over the hump to win the national majority in 1968 after losing in 1964, were the dixiecrats, but the white southern GOP were already there - stoked into action by the Goldwater exhortation about "states rights", which eventually evolved into the "southern strategy" (PDF).
The big change came in 1964 with Barry Goldwater and ''states' rights,'' a phrase and philosophy widely seen as anti-black and opposed by President Lyndon B. Johnson, the godfather of voting rights for blacks. In that Presidential election and the seven after, no Republican gained more than 15 percent of the black vote.

As a note - the oft-cited quote came from Bill Moyers, who served in several positions under Johnson including as Press Secretary. He penned an OpEd in the WP 30 years ago that said in part -
By Bill D. Moyers
November 13, 1988
WHILE Lyndon Baines Johnson was a man of time and place, he felt the bitter paradox of both. I was a young man on his staff in 1960 when he gave me a vivid account of that southern schizophrenia he understood and feared. We were in Tennessee. During the motorcade, he spotted some ugly racial epithets scrawled on signs. Late that night in the hotel, when the local dignitaries had finished the last bottles of bourbon and branch water and departed, he started talking about those signs. "I'll tell you what's at the bottom of it," he said. "If you can convince the lowest white man he's better than the best colored man, he won't notice you're picking his pocket. Hell, give him somebody to look down on, and he'll empty his pockets for you."
Some years later when Johnson was president, there was a press conference in the East Room. A reporter unexpectedly asked the president how he could explain his sudden passion for civil rights when he had never shown much enthusiasm for the cause. The question hung in the air. I could almost hear his silent cursing of a press secretary who had not anticipated this one. But then he relaxed, and from an instinct no assistant could brief -- one seasoned in the double life from which he was delivered and hoped to deliver others -- he said in effect: Most of us don't have a second chance to correct the mistakes of our youth. I do and I am. That evening, sitting in the White House, discussing the question with friends and staff, he gestured broadly and said, "Eisenhower used to tell me that this place was a prison. I never felt freer."
For weeks in 1964, the president carried in his pocket the summary of a Census Bureau report showing that the lifetime earnings of an average black college graduate were lower than that of a white man with an eighth-grade education. And when The New York Times in November 1964 reported racial segregation to be increasing instead of disappearing, he took his felt-tip pen and scribbled across it "shame, shame, shame," and sent it to Everett Dirksen, the Republican leader in the Senate.
I have a hard time explaining to our two sons and daughter -- now in their twenties -- that when they were little, America was still deeply segregated. The White House press corps, housed in Austin when the president was on vacation in Texas, would often go to the faculty club at the University of Texas, which was still off-limits to blacks in 1964. I remember the night it changed.

“Republicans” specifically, rather than low white men in general. I should have said there were then relatively fewer Republicans in the solid south when Moyers quoted LBJ instead of none.
I'm seeing that PA had the same number of electoral votes as CA in 1960. 
Now we have a bit more than 1/3rd (as of the 2010 census, CA had 55 and PA had 20).
The perception of white privilege unfortunately is not just a southern phenomenon.
