Idk about this. I think the main issue is social media and filter bubbles. Generative AI contributes, but enough fakes news is there anyways. People will also use real riot videos from 4 years ago and claim that's the LA riots. The Russian troll farms can do this with or without AI. Trump, too. They'll just come up with drinking bleach is good with their own brains.

I don't want to refute this. Generative AI accelerates it immensely and makes it easier and way more. But mind that the core of the problem is society, education and most of all social media.

Also this isn't exactly new, we had Cambridge Analytica since 2014 or something. And manipulating elections and politics by technology is even older than that.
