Mr. Kemp’s office removed 1.4 million names from the rolls starting in 2012, erasing a backlog he inherited. Still, active registrations grew from 5,033,307 when he was elected in 2010 to 6,428,581 last fall, a 27.7% increase. Much of this bump came after Mr. Kemp implemented automatic voter registration for Georgians who update or apply for their driver’s licenses. For her part, Ms. Abrams never worked to repeal the use-it-or-lose-it or exact-match law during her decade in the Georgia legislature. In fact, while she criticizes Mr. Kemp for reducing opportunities for early voting, she not only voted to require him to rein in early voting, but co-sponsored the 2011 law.

Upon examination, her “stolen election” claim is a sore loser’s excuse. Ms. Abrams admitted as much to the New York Times last month: “I have no empirical evidence that I would have achieved a higher number of votes.” That hasn’t stopped her from smearing her state. Nor has it kept Hillary Clinton, Elizabeth Warren, Robert Francis O’Rourke and Kamala Harris from echoing her scurrilous charge.

Like P.T. Barnum, Ms. Abrams puts on an entertaining show that’s richly rewarding—for herself. She creates nonprofits with noble-sounding names, hires herself, and fills the payroll with campaign staffers who enjoy paychecks between elections.
