Can it really be called "extreme" anymore? Europe is swinging strongly towards being anti-migration at the moment. Other parts of the world like Japan are also going through such swings. Many countries never opened their borders to begin with. This political party sounds like it's closer to the average than people would like to admit.
I was mostly going by the “far-right” classification in the title. If indeed the whole spectrum has switched it will be less extreme when viewed from within the spectrum.
They're so populist, in fact, that they require CEOs to donate them millions of dollars to constitute the backbone of their party. Oh wait, that's what political interest groups do.
