One of them has already embraced AI's truth-bending potential: Ron DeSantis's presidential campaign has circulated a video peppered with fake photos of Donald Trump hugging and kissing the controversial Dr. Anthony Fauci. 

The video includes bona fide images of Trump, but experts say three others are almost certainly AI-generated deep-fakes. "Our results consistently output a decision that these images are fake," Drexel University electrical and computer engineering professor Matthew Stamm told Reuters after using a process to scour the images for artifacts of synthetic image generation.  

After the fakery was reported, first by Agence France-Presse and then major US outlets, Trump allies were quick to condemn DeSantis.
