JD Vance, if elected, would become the 48th President of the United States, succeeding Donald Trump. Erika Kirk’s public backing of Vance is the clearest signal yet of potential conservative momentum behind his candidacy, as the political landscape begins to take shape for the upcoming election cycle.

Charlie Kirk, who founded Turning Point USA and emerged as a key figure in bridging gaps within the conservative community, left a profound impact before his untimely death in September. Erika Kirk’s leadership aims to preserve and build upon his legacy, positioning Turning Point USA as a pivotal player in national politics.

Vance would be the 48th president if he takes office after Trump.

Kirk’s statement on Thursday is the most explicit backing of Vance’s possible candidacy by a woman who has been positioned as a steward to her late husband’s legacy. Charlie Kirk had become a powerbroker and bridge builder within the conservative movement before he was assassinated in September.

Vance is set to speak to Turning Point on Sunday, the conference’s last day. The convention has featured the usual spectacle and energy that have characterized the organization’s events, but the proceedings have also been marred by intense infighting among conservative commentators and estranged allies who have turned on each other in the wake of Kirk’s death.
