When Chief Justice Earl Warren was asked at the end of his career, “What was the most important case of your tenure?”, there were a lot of answers he could have given. After all, he had presided over some of the most important decisions in the court’s history — cases that dealt with segregation in schools, the right to an attorney, the right to remain silent, just to name a few. But his answer was a surprise: He said, “Baker v. Carr,” a 1962 redistricting case. 

On this episode of More Perfect, we talk about why this case was so important; important enough, in fact, that it pushed one Supreme Court justice to a nervous breakdown, brought a boiling feud to a head, put one justice in the hospital, and changed the course of the Supreme Court — and the nation — forever.
