It's pretty easy: he started out trying to create a "hot girl" influencer, then refined that. It could be his starting point was biased towards filling a certain type of conservative fantasy, but wasn't as easily adaptable to progressives. For instance: it could be that lonely straight progressive men are more neurotic about their sexuality, and thus less-likely to respond positively to a bikini model picture, even if the "model" is flattering their political ideology.

Also there's been a demographic divergence, and young women are much more liberal than men, which means there's less of a supply of "hot girl" conservatives and more unfulfilled demand for them.

I suspect the progressive version of this is something a lot less discoverable by a random slop-making foreign man.
