It was the Republican Party that ushered in abolition, then emancipation and then voting rights. And blacks — virtually all blacks — became Republicans.
Democrats in Louisville, led by Courier-Journal editor Henry Watterson, were implacably opposed to blacks voting. Watterson wrote in the Courier-Journal that his opposition was "founded upon a conviction that their habits of life and general condition disqualify them for the judicious exercise of suffrage."
The first 20 African-American U.S. congressmen were all Republican. The Republican Party has had more African-American U.S. senators than have the Democrats.
One of those Republicans was Edwin Brooks of Massachusetts, who remarked that if Democrats had the incredible history of emancipation and election of African-Americans you'd hear about it non-stop.
The Republican Party's history is rich and chock full of black history and the fight for civil liberties.
I still believe in a Republican Party that has a zeal for equality before the law. A party that prizes the sense of justice that Martin Luther King, Jr. spoke of when he said: "an unjust law is any law the majority enforces on a minority but does not make binding upon itself."
