For more than three decades, Associate Justice John Paul Stevens was a tremendous force for justice and fairness on the Supreme Court.

A quick look at the Court's most controversial decisions, from Brown v. Board to Citizen's United v. the FCC, and it's clear that the appointment of a new Supreme Court Justice is among the most monumental decisions any president will make.

To replace John Paul Stevens -- a stalwart champion of constitutional values and the rule of law, and a man who served the court with compassion and integrity for more than 34 years -- will be a decision second to none.

Tell President Obama to appoint a justice who will keep faith with core constitutional values, stand for fairness under the law and defend our most important freedoms and protections -- a justice who will honor the legacy of Associate Justice John Paul Stevens.
