President Trump’s latest list of prospective Supreme Court nominees includes three U.S. senators: Josh Hawley of Missouri, Ted Cruz of Texas and Tom Cotton of Arkansas. This shows the president understands the need to appoint constitutional conservatives whose views won’t “evolve” once they are on the court.

The best way to do that is to nominate someone who has demonstrated that he won’t back down in the face of political threats (such as those made by Sens. Chuck Schumer and Sheldon Whitehouse earlier this year) and who has demonstrated that his principles are more important than being well thought of by the media or the politically correct.

Where should the president look to find such people? They can be found in the ranks of lawyers who have gone through the fire of political campaigns, been publicly attacked by the media and liberal opponents, and have held true to their beliefs through it all. Messrs. Hawley, Cruz and Cotton clearly meet this test.
