I don't think "Trump will ban porn if he gets elected" is a winning message with the entire electorate but it probably is a winning message if you want to damper the enthusiasm of the already-only- marginally-committed-to-voting Barstool/Manosphere frat dudes for Trump.
Suspect a big impetus to this push is an attempt to roll back the clock to the pre-internet days when the profits of porn distribution accumulated to the overlapping groups of local business tyrants, pimps and mobsters who owned the porn shops and strip clubs and prostitutes bsky.app/profile/jenn...
I think the bigger threat is not so much that the Right will go after internet porn but that they’ll define porn as “the existence of LGBTQ+ people in popular media such as books, TV and movies.”
