That was always the play. You say the things you would do if you were in your political opponents shoes, you talk about how bad it is, how horrible and wrong. And then, if you can manage to get enough political or monied support, you do the thing you said they were doing! After all, they did the thing first, right? It's just fair play, you say.
There was a good couple of months of mainstream media even touting that they're a threat to the left/progressive/less-conservative party currently in power who won the last election in no uncertain terms (maybe possibly a landslide...?).
It's hard to get a real gauge on it, but there's a very vocal minority that has been emboldened by Trump's anti-immigration, easy answers, point at 'other' as the cause of all the problems plaguing society rhetoric and actions, such that the 'more conservative' are at least getting more airtime, which makes it seem as if they're a "growing base". I know some people who have started talking a bit more openly in this direction.
The only real way to judge is an actual election.
Hungarians voted Orbán in, but they also voted him out even with Vance influence.
