In practical terms, the challenges to prosecuting Mrs. Clinton and her associates are formidable. The statute of limitations on lying and the immunity agreements her associates received are only some of the obstacles. Even more dispositive, criminally prosecuting an election loser isn’t going to help a nation that needs to move beyond 2016.

But Mr. Graham isn’t calling for Mrs. Clinton in prison stripes. He’s after something more fundamental. What he wants is for the American people to appreciate that men and women at the top of the nation’s intelligence and law-enforcement agencies abused the power of their respective offices by putting their fingers on the election scales.

Sen. Graham puts it this way: “I’m not so much worried about retrying her, but I want to make sure that the public understands that she got away with something they wouldn’t get away with.” And how much harsher the standard the same people applied to Mr. Trump.
