Until the rule is removed, any new posts about US politics will be removed.
There used to be dmv.social, which iirc was in Washington DC? It got shut down due to the CSAM attacks, before the automated software, and iirc just frustration in general with how toxic people were being.
And I see a bunch more actually, at https://lemmy.fediverse.observer. 2 of the top 20 instances even are located in the USA. Lemmy.sdf.org with >500 MAUs, beehaw.org with ~400, StarTrek.website with ~200, lemmy.today, ttrpgnetwork, and discuss.online (where jgrim of SubLinks is an admin) are all recognizable. Ofc, the caveat being if I am reading that page correctly - or like perhaps some proxy was used, even a random one and this data could be all wrong who knows - but it at least looks this way?:-)
