Something like this doesn't exist in Poland, well not in the shape or form it's in the US. At most if someone has the ability to, you will see officially printed banners from a party being hanged on someone's fence.
Here's an example how this even looks like, straight from a banner printing service: https://www.taniebanery.com.pl/
Of course they are an eyesore, a waste of materials, and are littered fucking everywhere during election season.
Okay, sometimes there's exceptions
But they aren't novelty items that are stylized to look like straight out of Barbie.
So again. Why the fuck is America such a weird and wild country? Why the fuck would anyone promote a politician out of their own pocket in a "quirky" and "cutesy" or "relatable" way???
Jesus I hate the US. Yes this is a bit of a vent post, cry about it :3
Idk I have literally never seen anything like that as a US native. I have only seen what appear to be official, standard political yard signs. That said, I have definitely seen a variety of stupid fash flags/stickers/shirts, etc - like trump flags, confederate flags (pro slavery/apartheid, basically), "lets go brandon", white lives matter, thin blue line (pro cop), various pro gun slogans like "come and take it" (which could be based but mainly far right/fascists use these). Some people have flag poles in their yards, and a minority of those will display flags like these. More will wear clothing or have stickers on their cars.
