The Mi Hazánk brings a very typical right radical form, with the 5-7%. These voters probably those who doesn't like the Jew-love of the Fidesz, and those who have struggles with the Gypsies. They won't ever get a real voice nowhere. But this 5% is about the same since the MIÉP (the first such party) was founded 1993. Jobbik had a growth when they dialed down the rhetoric and went softer, taking many voters with conservative tendencies and aversion of Fidesz. These now vote on the Tisza.
The DK hanging on is fantastic. There are still some people who prefer them. Pensioners? I dunno. I'm fairly sure young voters would rather pick KKP, Momentum, MMN, Greens, or LMP than them. But they are probably drift towards the Tisza instead.

And back to the TISZA Párt.
As I mentioned before I "get to" listen to the radio this year, and literally all is Fidesz propaganda. If it's about the opposition then it's Magyar Péter constantly. So much shit they pour onto him, that's hilarious. And really activates those braincells. They add to the hype. And if the Fidesz really "hates" someone, that makes those who hate the Fidesz support that person. It's the "Dirty Fred effect" - as I call it, based on a character of old Hungarian pulp fiction novels, where Dirty Fred (a kind of an antihero) used his own unpopularity to influence others to help someone whom he wanted to help. We could call this reverse psychology.
I believe the reason behind the hype around Magyar Péter is that the Fidesz wants to keep the opposition afloat, so they can keep up the appearance of democratic legitimacy. The previous opposition parties just couldn't keep their voterbase.
By how much this party is "controlled" as they say. I dunno. But the voters have real antipathy towards Fidesz.
