European nationalism succeed in Eastern Europe, Italy and Slovakia. The far right is expected to do well in E.U elections as well. I doubt as a whole white nationalism will succeed in France, Germany or UK though. Too many brainwashed white liberals [and Jews] in those neck of the woods as well.

The Republican/MAGA wing of the GOP can't succeed long term in the USA because 30% of voters are either non-whites or Jews. Then you add in race-mixers, atheists/agnostics (i'm agnostic myself btw) , whites who have voted democrat for generations (the Vermont, Michigan and Maine type), professors, the "hollywood" type whites and it gets even harder to win elections as a nationalist.

Thats why democrats won in 2018, 2020, 2021 GA senate run off, 2022 and in most special elections. That's why Republicans are struggling to keep the house and democrats made inroads in state legislators in recent elections. Thats why I don't think Trump will win in 2024. All the groups I mentioned vote democrat over 70% of the time.
