The passing of Senator Lindsey Graham at 71 marks the end of a consequential chapter in American politics. Graham, who represented South Carolina in the United States Senate for more than two decades, died following what his office described as a brief and unexpected illness.

I did not agree with Graham on every issue. At times, I strongly disagreed with his approach to foreign policy, the Republican Party, and the role of the political establishment. But political disagreement should not prevent us from recognizing a lifetime of service or the undeniable impact that one person had on our country.

Graham dedicated virtually his entire adult life to public service. He served as an Air Force lawyer, represented South Carolina in the House of Representatives, and then spent more than two decades in the Senate. He never married or had children, and public life appeared to become his life’s central commitment.

He was also undeniably intelligent, politically skilled, and willing to defend the institutions he believed were essential to the country.

Perhaps no moment better represented Graham’s legacy than the confirmation hearings of Supreme Court Justice Brett Kavanaugh.

As Kavanaugh faced baseless sexual-misconduct allegations that threatened to destroy his reputation and derail his nomination, many Republicans appeared hesitant to challenge the political narrative surrounding the hearings. Graham did not hesitate. His forceful defense of Kavanaugh became one of the defining moments of the confirmation battle.

Regardless of how one views Graham’s broader record, his response demonstrated that he understood two important principles: allegations alone should not erase the presumption of innocence, and the Supreme Court should not be transformed into a weapon of partisan personal destruction.

Graham was often criticized for being an institutionalist. Some of that criticism was justified. Institutions can become detached from the people they are supposed to serve, and defending them simply because they exist is not always virtuous.

But Graham also understood something that modern politics often forgets: not every institution is inherently corrupt, and preserving the legitimacy of constitutional institutions is necessary for the country to function. His defense of Kavanaugh was not merely a defense of one nominee. It was a defense of due process and the integrity of the confirmation process.

Graham was also among the relatively few Republican senators who maintained meaningful relationships with Democrats. His willingness to negotiate frustrated many conservatives, including me. Yet it also reflected his belief that political opponents could disagree without treating one another as enemies.

Almost exactly one year ago, I interviewed former South Carolina Lieutenant Governor Andre Bauer, who was challenging Graham in the Republican primary. Bauer later withdrew from the race and has since been nominated to serve as the United States ambassador to Belize.

Following Graham’s passing, Bauer told me that politics should now take a back seat to recognizing the senator’s decades of service.

“Public service is not an easy calling,” Bauer said. “It requires long hours, personal sacrifice, and an enduring commitment to something larger than oneself.”

Bauer added that while Graham’s legacy will be debated for years, “there should be no debate about his dedication to South Carolina.”

That is the proper way to remember Lindsey Graham.

His positions, alliances, and decisions will continue to be examined and criticized. That is inevitable for anyone who spends decades wielding political power. But Graham’s life should also remind Americans that disagreement does not require hatred, and criticism does not prevent respect.

Lindsey Graham believed in what he advocated, fought forcefully for his convictions, and devoted his life to his state and country. Americans did not have to agree with him to recognize the magnitude of that commitment.
