If anyone is actually really interested in the party switch, here is some reading:
Hubert Humphrey's 1948 DNC Convention Speech
"My friends, to those who say that we are rushing this issue of civil rights, I say to them we are 172 years late. To those who say that this civil-rights program is an infringement on states’ rights, I say this: The time has arrived in America for the Democratic Party to get out of the shadow of states' rights and to walk forthrightly into the bright sunshine of human rights. People -- human beings -- this is the issue of the 20th century. People of all kinds -- all sorts of people -- and these people are looking to America for leadership, and they’re looking to America for precept and example."
This speech caused Strom Thurmond to storm out of the convention and run as a Dixiecrat on a platform of segregation. Thurmond of course, would later become a Republican (remember when Trent Lott had to step down as Majority Leader when he said the country would be better off if Thurmond won??? Different times man).
Next, Jackie Robinson (yes, that Jackie Robinson!) and Barry Goldwater
"But Republican leaders weren’t looking for a black messiah, and in the following year, Robinson implored Nixon to counter Barry Goldwater’s white-centered politics. “We’re not going to get the Negro vote as a bloc in 1964 and 1968, so we ought to go hunting where the ducks are,” Goldwater had said. That divisive statement, Robinson wrote Nixon, “will be Republican policy until someone other than Goldwater vigorously denies that the Republican Party is not interested in the Negro vote.”
Nixon did not come through, and Robinson’s disappointment only deepened when the Republicans nominated Goldwater for president in 1964. “His candidacy reeks with prejudice and bigotry,” Robinson wrote.
Warning that Republicans were forming a “white man’s party,” Robinson then supported the Democratic Lyndon Johnson-Hubert Humphrey ticket in 1964. But he drifted back to the Republican fold once again in the mid-1960s, this time focusing his lobbying efforts on his all-time favorite politician, Republican governor Nelson Rockefeller of New York. “The sooner there is a strong two-party system in New York as well as nationwide, the sooner we get our rights,” he penned to Rockefeller in 1965."
Robinson would later support some other Republicans, but he recognized how terrible Goldwater was for the party.
This article has a lot of good quotes from black newspapers during the time.
“During my life, I have had a few nightmares which happened to me while I was wide awake,” Robinson wrote in 1967. “One of them was the National Republican Convention in San Francisco, which produced the greatest disaster the Republican Party has ever known—Nominee Barry Goldwater.” Robinson, a loyal Republican who campaigned for Richard Nixon in 1960, was shocked and saddened by the racism and lack of civility he witnessed at the 1964 convention. As the historian Leah Wright Rigueur describes in The Loneliness of the Black Republican, black delegates were verbally assaulted and threatened with violence by Goldwater supporters. William Young, a Pennsylvania delegate, had his suit set on fire and was told to “keep in your own place” by his assailant. “They call you ‘nigger,’ push you and step on your feet,” New Jersey delegate George Fleming told the Associated Press. “I had to leave to keep my self-respect.”
As the Draft Goldwater campaign expanded in early 1963, the editors at the Chicago Defender warned that Goldwater’s “brand of demagoguery has a special appeal to ultra conservative Republicans” and that he “cannot be laughed off as a serious possibility as is being done in some quarters unfriendly to him.” After the 1964 Republican National Convention, the Defender suggested, “Goldwater in the White House would be a nightmare from which the nation and the world would not soon recover.” Another editorial two days later struck a stronger tone: “The conviction is universal that Goldwater represents the most diabolical force that has ever captured the leadership of the Republican Party. After 108 years of exhortation to freedom, liberty, and justice, the GOP now becomes the label under which Fascism is oozed into the mainstream of American politics.” (pretty fucking prescient, eh?)
And last, for anyone who still thinks the Civil War wasn't about slavery, let me present the Cornerstone Speech, by the Confederate Vice President, Alexander Stephens
"Our new government is founded upon exactly the opposite idea; its foundations are laid, its corner- stone rests, upon the great truth that the negro is not equal to the white man; that slavery subordination to the superior race is his natural and normal condition. This, our new government, is the first, in the history of the world, based upon this great physical, philosophical, and moral truth."
"It is, indeed, in conformity with the ordinance of the Creator. It is not for us to inquire into the wisdom of His ordinances, or to question them. For His own purposes, He has made one race to differ from another, as He has made "one star to differ from another star in glory." The great objects of humanity are best attained when there is conformity to His laws and decrees, in the formation of governments as well as in all things else. Our confederacy is founded upon principles in strict conformity with these laws. This stone which was rejected by the first builders "is become the chief of the corner" the real "corner-stone" in our new edifice."
