The article talks about how Republicans are alienating virtually every woman in the country. So, to appear electable, they’re having their wives and kids do the ads, so that out-of-touch women will see a woman in the ad and decide that the candidate is a good guy.
But that, and the whole focus on “traditional family values” and everything boxes them into a certain image, that you’re not a real American man if you’re not married with kids by the time you’re in your 30s or something. So, even if he had a picture with his fiance and dog, it would prove he’s not a “traditional family values” republican. So, better to pose with a friend’s wife and kids than prove that he’s not “normal”.
At least it adds noise to the system. It’s better than the people who are happily training the AI.
