Only one Supreme Court Justice has ever served longer than Clarence Thomas

The first baby boomer on the Supreme Court hit a milestone on Thursday, becoming the second-longest serving justice in history at a time when his influence has never seemed greater. Once an outlier on the nation’s highest court, Justice Clarence Thomas has become a towering figure in the conservative legal movement over the last decade as he helped secure landmark rulings on abortion, voting and Second Amendment rights. The only justice with a longer tenure is liberal William O. Douglas. Thomas would overtake Douglas in 2028 if he remains on the court — and there’s no sign he plans to retire anytime soon. “I think he’s more energized and excited now than when I first met him,” said John Yoo, a law professor at the University of California, Berkeley, who served in Republican President George W. Bush’s administration after his time as a Thomas clerk three decades ago. Thomas was confirmed in 1991 after contentious hearings that included sexual harassment allegations. More recently, his acceptance of luxury trips has raised a storm of ethics questions. He’s nevertheless gone from near-silence at oral arguments to asking the first questions and penning a landmark ruling expanding Second Amendment rights. Following the appointment of three conservative justices by Republican President Donald Trump, Thomas is now the most senior member of a supermajority that’s also overturned abortion as a constitutional right, ended affirmative action in college admissions and sharply limited the Voting Rights Act. “The court has radically moved in his direction over the course of his time on the court,” said Stanford University law professor Pamela Karlan. Thomas’ seniority means he can decide who writes an opinion if he’s part of a majority that doesn’t include Chief Justice John Roberts, a factor that can nudge other votes behind closed doors, Karlan said. Off the bench, Thomas’ sphere of influence also includes his large, close-knit network
