As John Roberts begins his second decade as the chief justice, a number of Supreme Court rulings during his tenure are once more in the news, perhaps none more so than Citizens United v. Federal Elections Commission. The 5-4 decision, which applied First Amendment guarantees of freedom of speech to a private corporation, has been targeted lately by Democrat presidential candidates Hillary Clinton (“Citizens United was about me. Think how that makes me feel.”) and Bernie Sanders, who declared this week, “No nominee of mine to the United States Supreme Court will get that job unless he or she is loud and clear that one of their first orders of business will be to overturn Citizens United." Americans are equally hostile to the decision: A national poll released by Bloomberg Politics this week found that 78 percent of respondents want Citizens United overturned, while only 17 percent support the ruling.

What many Americans might not know, however, is that the manner in which corporations came to be granted personal rights is inextricably linked to a series of late nineteenth century Supreme Court rulings that disemboweled the Fourteenth and Fifteenth amendments and ushered in the Jim Crow era, when state and local laws were passed to create racial segregation.

The Fourteenth Amendment, ratified in 1868, was aimed at securing fundamental rights for the four million newly freed slaves. Section 1 conferred citizenship on any person born in the United States, made them citizens of the state in which they resided, and guaranteed all Americans “due process of law” and “equal protection of the laws.” To the man who drafted that section of the amendment, Representative John Bingham of Ohio, this meant that the personal guarantees of the Bill of Rights would apply to state as well as federal law. Most in Congress who voted for the amendment agreed, and we take such guarantees against state action for granted today. And the Fifteenth Amendment, of course, guaranteed black men the right to vote.

But after Chief Justice Salmon P. Chase died in 1873, protections for black Americans began to unravel, all enabled and often mandated by the Supreme Court.

President Ulysses Grant had a great deal of difficulty filling Chase’s seat. Having failed three times to find an acceptable candidate, he settled on Morrison R. Waite. It was not a choice based on excellence. Waite was described by Grant’s attorney general as “sufficiently obscure for the occasion,” and characterized by the Nation as firmly “in the first rank of second rank lawyers.” Stung by the criticism and determined to make his mark, Waite decided to author the majority opinion in the most inflammatory case on the 1876 docket, United States v. Cruikshank.
