"As a former Republican political operative who worked in South Carolina presidential primaries, I look at Ms. Haley now, as she prepares to launch her own presidential campaign, with sadness tinged with regret for what could have been. But I’m not a bit surprised. Her rise and fall only highlights what many of us already knew: Mr. Trump didn’t change the Republican Party; he revealed it. Ms. Haley, for all her talents, embodies the moral failure of the party in its drive to win at any cost, a drive so ruthless and insistent that it has transformed the G.O.P. into an autocratic movement. It’s not that she has changed positions to suit the political moment or even that she has abandoned beliefs she once claimed to be deeply held. It’s that the 2023 version of Ms. Haley is actively working against the core values that the 2016 Ms. Haley would have held to be the very foundation of her public life."
