DiogenesLamp, I think you’re missing the direction of my post, and you and I are in agreement. The “party switching” lie refers to the idea that Democrats and Republicans “switched sides” as part of Nixon’s Southern Strategy, which supposedly the impetus of was the Civil Rights Act of 1964. This is the big lie. And you’re right, Johnson’s tactics with the black population was the biggest bamboozle in the history of this country.
...and a total disgrace to the black population.
Funny you brought up Nixon’s “Southern Strategy” which is another lie. Nixon won in 1968 because Former Democrat and 3rd party George Wallace carried the South, splitting the Democrat (aka:the Racist) vote and throwing the win to Nixon. Not that he needed it if you look at a 1968 Electoral Map.
Barry Goldwater did come out against the Civil Rights act of 1964 on the basis that it would lead to future abuse. (It has.) Because he was the Republican nominee in 1963, the Democrats started tagging Republicans as "Racist".
When Nixon was implementing his "Southern Strategy", this just fed further into the smear.
But getting back to the point about the parties switching, My point was to say it's not completely untrue, that there is some truth in the claim that the "parties switched". Sort of, depending on how you look at it.
Also in the 1920s onward, blacks started moving more into the cities, which also tended to align them with Wealthy Urban Liberals.
