While age discrimination is illegal in the workplace, it ought to be a guiding principle in the Oval Office as President Trump swipes through a catalog of potential Supreme Court nominees.

The ideal nominee will have the mind of Clarence Thomas and the wit of Antonin Scalia. But even more important is the longevity of Ruth Bader Ginsburg. Just like her, the nominee ought to be prepared to live and serve for as many decades as possible.

Judging from Trump’s list of Supreme Court candidates, it’s clear he has a type: young. Ten of the 26 potential nominees are under 50. The youngest of those is an Oklahoma Supreme Court justice named Patrick Wyrick. He just turned 37 years old last March and makes Justice Neil Gorsuch look like an old man.

It is easy to be blinded by youth. In the coming months, though, this White House must be guided by it. Republicans are about to replace their oldest justice, leaving that role to Clarence Thomas at age 70. But Democrats have two justices who were born during FDR's presidency.

In short, Trump has an opportunity to tip the balance of the high court for several generations. Below is his shortlist, sorted by age:

Patrick Wyrick of Oklahoma, Supreme Court of Oklahoma (37)

Britt Grant of the Supreme Court of Georgia (40)

Keith Blackwell of the Supreme Court of Georgia (42)
