“Yet the harsh fact is that in many places in this country men and women are kept from voting simply because they are Negroes … No law that we now have on the books …can insure the right to vote when local officials are determined to deny it.”

1960s, Special message to Congress on the right to vote (1965)
Context: The essence of our American tradition of State and local governments is the belief expressed by Thomas Jefferson that Government is best which is closest to the people. Yet that belief is betrayed by those State and local officials who engage in denying the right of citizens to vote. Their actions serve only to assure that their State governments and local governments shall be remote from the people, least representative of the people's will and least responsive to the people's wishes.

Context: Looking back over the whole policy of reconstruction, it seems to me that the wisest thing would have been to have continued for some time the military rule. Sensible Southern men see now that there was no government so frugal, so just, and fair as what they had under our generals. That would have enabled the Southern people to pull themselves together and repair material losses. As to depriving them, even for a time, of suffrage, that was our right as a conqueror, and it was a mild penalty for the stupendous crime of treason. Military rule would have been just to all, to the negro who wanted freedom, the white man who wanted protection, the northern man who wanted Union. As state after state showed a willingness to come into the Union, not on their own terms but upon ours, I would have admitted them. This would have made universal suffrage unnecessary, and I think a mistake was made about suffrage. It was unjust to the negro to throw upon him the responsibilities of citizenship, and expect him to be on even terms with his white neighbor. It was unjust to the north. In giving the south negro suffrage, we have given the old slave-holders forty votes in the electoral college. They keep those votes, but disfranchise the negroes. That is one of the gravest mistakes in the policy of reconstruction. It looks like a political triumph for the south, but it is not. The southern people have nothing to dread more than the political triumph of the men who led them into secession. That triumph was fatal to them in 1860. It would be no less now. The trouble about military rule in the south was that our people did not like it. It was not in accordance with our institutions. I am clear now that it would have been better for the north to have postponed suffrage, reconstruction, state governments, for ten years, and held the south in a territorial condition. It was due to the north that the men who had made war upon us should be powerless in a political sense forever. It would have avoided the scandals of the state governments, saved money, and enabled the northern merchants, farmers, and laboring men to reorganize society in the south. But we made our scheme, and must do what we can with it. Suffrage once given can never be taken away, and all that remains for us now is to make good that gift by protecting those who have received it.

2015, Commemoration of the 150th Anniversary of the 13th Amendment (December 2015)
Context: At its heart, the question of slavery was never simply about civil rights. It was about the meaning of America, the kind of country we wanted to be –- whether this nation might fulfill the call of its birth: “We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights,” that among those are life and liberty and the pursuit of happiness. President Lincoln understood that if we were ever to fully realize that founding promise, it meant not just signing an Emancipation Proclamation, not just winning a war. It meant making the most powerful collective statement we can in our democracy: etching our values into our Constitution. He called it “a King’s cure for all the evils.” A hundred and fifty years proved the cure to be necessary but not sufficient. Progress proved halting, too often deferred. Newly freed slaves may have been liberated by the letter of the law, but their daily lives told another tale. They couldn’t vote. They couldn’t fill most occupations. They couldn’t protect themselves or their families from indignity or from violence. And so abolitionists and freedmen and women and radical Republicans kept cajoling and kept rabble-rousing, and within a few years of the war’s end at Appomattox, we passed two more amendments guaranteeing voting rights, birthright citizenship, equal protection under the law.
