From the National Black Republican Association:
From its founding in 1854 as the anti-slavery party until today, the Republican Party has championed freedom and civil rights for blacks. And as one pundit so succinctly stated, the Democrat Party is as it always has been, the party of the four S's: Slavery, Secession, Segregation and now Socialism.
It was the Democrats who fought to keep blacks in slavery and passed the discriminatory Black Codes and Jim Crow laws. The Democrats started the Ku Klux Klan to lynch and terrorize blacks. The Democrats fought to prevent the passage of every civil rights law beginning with the civil rights laws of the 1860's, and continuing with the civil rights laws of the 1950's and 1960's
During the civil rights era of the 1960's, Dr. King was fighting the Democrats who stood in the school house doors, turned skin-burning fire hoses on blacks and let loose vicious dogs. It was Republican President Dwight Eisenhower who pushed to pass the Civil Rights Act of 1957 and sent troops to Arkansas to desegregate schools. President Eisenhower also appointed Chief Justice Earl Warren to the U.S. Supreme Court which resulted in the 1954 Brown vs. Board of Education decision ending school segregation. Much is made of Democrat President Harry Truman's issuing an Executive Order in 1948 to desegregate the military. Not mentioned is the fact that it was President Eisenhower who actually took action to effectively end segregation in the military.
Democrat President John F. Kennedy is lauded as a proponent of civil rights. However, Kennedy voted against the 1957 Civil rights Act while he was a senator, as did Democrat Senator Al Gore, Sr. And after he became president, John F. Kennedy was opposed to the 1963 March on Washington by Dr. King that was organized by A. Phillip Randolph who was a black Republican. President Kennedy, through his brother Attorney General Robert Kennedy, had Dr. King wiretapped and investigated by the FBI on suspicion of being a Communist in order to undermine Dr. King.
