Obviously we don't know yet, but I would be absolutely shocked if they don't basically flag everything about well-known politicians as "political", and paying to boost something like that should fall under the new restrictions. It would be trivial for most large tech companies to make an automatic "political post" classifier at this point. The post "boosting" use case is a pretty easy target too because blocking someone from paying to boost something is fairly low-risk.

You'd be surprised at how influential memes are these days ... as ridiculous as it is to consider, they are absolutely political speech, and can be used as propaganda.
