Far right candidates are running and are likely to win all over Europe.
Not really. The far right came out of the woodworks because of the refugee crisis and how dissatisfied a lot of people are with how it is handled. They'll try to get support playing the "Us vs them" card, but just because they're loud and protesting doesn't mean that they suddenly get a huge surge in support and popularity. The support for the far right is marginal in most of Europe. Also, most countries in Europe have a multiple party system, meaning that the parliaments are made of 5-7 different parties usually. Not like the US where you have either Republicans or Democrats making up the majority of the government body. In some European countries a far right party might get into the parliament, but their seats will be in low numbers and they will be outnumbered by other more moderate right, left and middle parties, that will block any attempt of the far right doing anything.
Anyway, since this is a thread about a yuri manga, I just want to say that I like the idea of the story being set in LA. Most of the media influence comes from the US nowadays with movies, tv shows, music etc., so it's not surprising that the mangaka chose the US instead of a European country. As a Euro, I can live with that and approve.
