Politics is everywhere, but the state of US politics today is exceptionally bad by Western world standards. I hate the government in my country, but their corruption and incompetence is nothing compared to the Trump administration.
In that sense most EU countries are a positive upgrade.
People also embed themselves in different communities when they move anywhere, even to a different city or state in the same country. It's a clean reset.
It doesn't always last forever. I know several people who tried to move somewhere, including internationally, when politics got heated in 2016. Most of them came back eventually with a realization that politics is everywhere, it's just a matter of how much you're embedded into the places it's discussed.
