You...and Barry Goldwater.
The Voting Rights Act was passed in 1965. The Republican candidate for President in 1964, Barry Goldwater, loudly objected to the terms of the act and, in the end, voted against it.
His argument was that all the provisions of the act should apply equally, everywhere -- not just in the states and counties with a "history of discrimination". He noted that the Constitution seemed to demand such an outcome.
But it was passed anyway. And, having voted against it, the Democrats (and their compliant media) labelled Goldwater a racist.
Which is one of the major reasons why blacks are anti-Republican today -- even though the GOP members in the Senate voted 30-2 in favor of the bill (and voted 32-0 for cloture, breaking the Democrat filibuster against the bill).
The civil rights movement of the 1960s spurred a generational and cultural discontinuity in the Black community parallel to that among whites. In both instances, Republicans were on the side of tradition, order, and more gradual progress, and opposing street protests against the Viet Nam war and disorderly mass civil rights protest marches.
In both instances, the new cultural and political loyalties among the young who embraced such protests accrued to the enduring benefit of the Democrats and the Left. A new generational shift will soon be underway though when young people realize that they have been handed the bill for their elders' unsustainable Medicare and Social Security benefits, with a future further constrained by a dismal regulatory and tax structure fashioned by the Left.
