Jobbik went from far-right to center-right when Fidesz radicalized itself so much that there wasn't any point to being on the far-right anymore if you actually had any aspirations of winning the election, which Jobbik certainly during the 2010s.
And now we got a new far-right party instead of Jobbik, outside of the united opposition, but they don't have the same large voter base. Jobbik had 20% of the votes for two elections (and maybe even 30% at some point between the elections), the current far-right party got 6%.
Anyway, maybe the opposition learned its lesson this time: change comes from the left, not from the right. Hungary needs a healthy left-wing that can stand on its own, without parties like Jobbik. As long as the left-wing is a shadow of its former self, without any new leaders and new ideas, Orbán will never have a real opponent in Hungary.
