The problem is that many of these content are image-only (titles don't always include names), requiring some kind of extension/userscript that's able to do some kind of OCR or Computer Vision. You can block specific communities or users, but this will also block potentially good threads (not everybody that's posting about politics is necessarily a politics-only user, same goes for communities such as !nostupidquestions@lemmy.world that aggregate both political and non-political content).

While there are communities explicitly and specifically focused on politics that can be blocked outright, there's no easy way to block every single political content without some kind of sophisticated client-side AI (which is error-prone).

Not sure about default but I'm using Sync and it's got a keyword filter. Using it to block Musk and Trump, made a big difference.

There doesn't seem to be as much overflowing into non political communities here as at reddit where it's just overflowing everywhere I find. I think it's a reflecting of the anxiety many are feeling about the election. Hopefully it dies down in a couple of weeks.

I'm a US citizen and I wish I could avoid it.

I just block most political comms, I don't see too much of it I would say.

Use the keyword filter. First of all add the last names of the candidates. And also "voting", "election". I'm happy with the amount of posts that remain after that.

Learn to enjoy it. Get the popcorn out and watch America burn 😎🍿

Yeah, keyword list would be awesome.

I have a personal bunch of communities as is allowed and occasionally jump to main when I run out of content. Usually see something I regret, often Trumpian, amusing but depressing. Maccas window Trump etc. Will code for relief if it's not too (ironically) political.
