Which Supreme Court justices are likely to retire next?

Who are the Supreme Court justices?

Nine justices make up the Supreme Court. Here's a look at all nine justices who make up the U.S. Supreme Court, including the newest Associate Justice Ketanji Brown Jackson.

The Supreme Court ended its term July 1 after handing down a cluster of consequential opinions in a busy final few weeks.

Meanwhile, Americans revealed in a new poll a lack of confidence in the high court and their handling of key issues before them.

Political experts are theorizing that whoever wins the presidential election could have a chance to fill one or two vacancies on the Supreme Court, a theory that even President Joe Biden has drawn attention to.

Who could those justices be, and would they be more likely to retire under a Biden presidency or a Trump presidency? Here is where each justice stands with his or her career, and the likelihood of retirement:

Justice Sonia Sotomayor

Although Justice Sonia Sotomayor isn’t the oldest or longest-serving justice on the bench, she’s the one some Democrats are zeroing in on to strategically retire under a Biden presidency.

Sotomayor, 70, was nominated by President Barack Obama, so she’s served for 15 years, which is in line with the average length of a Supreme Court Justice career.

Some political pundits are calling for her to retire now under Biden’s presidency to guarantee a Democratic president can name her successor.

Justice Elena Kagan

In the middle of the group age-wise at 64, Justice Elena Kagan has also seen some calls to strategically retire under a Biden presidency for the same reason.

She’s served on the court for just about as long as Sotomayor has, being appointed in 2010.

Justice Clarence Thomas

At 76, Justice Clarence Thomas is the oldest serving justice and is among the longest serving associate justices ever. He’s been on the court since 1991, marking a 33-year career on the court. The associate justice with the longest career was William Douglas, who served for 36 years until 1975.

Given those two factors, Thomas is the most favorable justice from a career standpoint. Given his well-known conservative standing and that he was nominated by a Republican president, he’d be more likely to retire under a Trump presidency.

Justice Samuel Alito

At 74, Justice Samuel Alito is the next oldest serving justice and has been on the court for 18 years.

He could also be a likely candidate to soon retire. Given his conservative standing and that he was nominated by a Republican president, he’d be more likely to retire under a Trump presidency.

Chief Justice John Roberts Jr.

At 69, Chief Justice John Roberts Jr. is among the older justices and has been on the court for 17 years.

He could also be a likely candidate to soon retire. Given his conservative standing and that he was nominated by a Republican president, he’d be more likely to retire under a Trump presidency.

Justice Neil Gorsuch

At 59 years old and only seven years into his Supreme Court career, Justice Neil Gorsuch isn’t a likely candidate to retire.

Justice Brett Kavanaugh

At 56 years old and only six years into his Supreme Court career, Justice Neil Gorsuch isn’t a likely candidate to retire.

Justice Amy Coney Barrett

At 52 years old and only four years into her Supreme Court career, Justice Amy Coney Barrett isn’t a likely candidate to retire.

Justice Ketanji Brown Jackson

At 53 years old and only two years into her Supreme Court career, Justice Ketanji Brown Jackson isn’t a likely candidate to retire.
