I recently watched videos of Bernie Sanders, who americans call left-wing, and maybe compared to other american politicians he is, but compared to russian opposition he is very like Boris Nemtsov and Alexey Navalny. First is literal founder of Union of Right Forces, second is considered to be center-right.
Two things I’ve noticed about American politics: first, the most left-wing American politician would be seen as borderline far right in Europe. Second, in the US there’s no left, because left would imply socialism that eventually lead to communism and that goes against the ideia of America, the American dream, the constitution etc. The entire country was built and maintained on the ideia of being against any form of communism.
