This isn't right wing, it's a bunch of small xenophobic far-right parties whose main platform theme is OMG EU SUCKS!
I thought the majority of Europeans thought "OMG EU SUCKS"?
Not sure if a majority hate it to that extent, but I'd think quite a lot do think it sucks, mainly because it tries to act as a large supranational very complexly organized. Few people actually know what the Commission, Parliament, etc. all do.
Maybe if they made it user-friendly and stopped regulating everything from fishing to sewers it could be more popular.
