Civil Rights: The pride and shame of both parties

On June 11, 1963 John F. Kennedy addressed the nation concerning civil rights.   Kennedy’s speech laid the foundation for The Civil Rights Act of 1964, legislation opposed by the Republican presidential candidate Barry Goldwater.
Goldwater’s opposition made the Democratic Party the logical choice for Blacks, and since the 1964 election the Democrats have portrayed their party as the sole champion of civil rights.
But is this historically accurate?
The Republican Party is known as the party of Lincoln, but there’s a forgotten faction—The Radical Republicans.  They were the progressives of their era that spearheaded the first civil rights act in 1866.  That bill granted Blacks legal rights, but it excluded the right to vote.
