( im not getting into that now)
So why do most black people swing left ?
Why are So Many Black Voters
Democrats, Even When They Aren’t Liberal?
Well, for one thing, the traditional values that most black Americans were at one time raised on stopped being transmitted from one generation to another with the breakdown of the black family, including the dramatic plunge in black marriage rates and the huge rise in teen pregnancy and single-motherhood among black Americans. This coincided with and was probably facilitated by LBJ's Great Society programs, which, whatever their intention, arguably marginalized the importance of black fathers. The Great Migration, in which blacks moved en masse from the South to the North in search of opportunities may have also served to alienate them from the cultural values of previous generations, while exposing them to all the dangers and temptations of urban life, all complicated of course, by the difficulties guaranteed by their skin color.
Couple that with the fact that lower income blacks, while not as in touch with the values of their prior generations by fractured family unit, are largely at the mercy of the public school system for their education as well as the media and you have the recipe for a people who are going to be exposed almost exclusively to leftist thought while at the same time being increasingly alienated from cultural institutions such as the black church and the family values of the past.
My mother is a die-hard Democrat, but at the same time, at 79, she is still, in many ways, steeped in the cultural traditions of Southern blacks. What many people take to be "authentic" black culture is largely alien to her and it would absolutely horrify my grandmother. Many blacks of past generations, such as my grandmother, would never, ever put party loyalty above their faith; near death, she had determined to vote for George W. Bush, convinced of his character and most importantly, of his piety. Those cultural values, including the strong role of the Church, in some ways served as a counter-balance to the natural pull that leftism is going to have on any discriminated minority group. Sadly, as I said, the influence of leftism, both of the pop-culture variety and the academic sort, has grown, while the black family has dissolved and the black church's influence has been eroded and is even actively fought by some.
That at least, is part of the reason why leftism has such a strong influence among blacks, in my opinion.
A more simple reason as to why most blacks vote Democrat is that, in spite of their loyalty to Lincoln's party, a majority of blacks were convinced by the promises of Roosevelt's New Deal to vote Democrat. In that case, the switch was born of a perceived economic necessity. Later on, although far more Republics supported Civil Rights and integration than did Democrats, Barry Goldwater voted against the Civil Rights Act of 1964 and earned the ire of Martin Luther King, further cementing the Democrat hold on black voters.
There was also the nascent radicalism of the 60's that grew into a significant force, gaining power and authority from the momentum of the Civil Rights movement. Black and white volunteers who joined less radical groups like SNCC to help register black voters in the South were in fact murdered by racists and even the victims of car bombs in some instances. These legitimate and profound grievances, not to mention the site of non-violent protesters beaten by police, certainly fed into the fury that led people--including my Aunt--to join avowedly Marxist groups such as the Black Panthers.
Unfortunately, after the 60's, their influence remained and was reinforced by a sort of one-two punch of Tupac Shakur on the TV and Assata Shakur in the classroom. Meanwhile, for reasons I already mentioned, the prior traditional values--which didn't stop blacks from voting Democrat but did stymie the cultural dominance of leftism--became ever weaker.
