What does this election means for the future?
Unsure.

The Tisza promised a big housecleaning. They have the power to change the constitution (they have the power to mangle it or create a new one) and they have the legitimization to do legally questionable things as well, sidestepping certain norms.
Magyar Péter said things that may temper some (foreign) expectations. He said he doesn't want Ukraine to join EU in the near future. He said we still keep buying Russian oil. He said we still won't be part of taking the €90 billion loan on - tho he won't prevent it, but in return we need the EU gibsmedats.
They'll probably took out some parts form the constitution about hetero marriage and God and Jesus or soemthing. Tho recently I head some promises that nothing such will happen.

They gonna have problems.
The economy ain't doing good and the EU gibsmedats won't help much. They will learn what numbers they can work with, and what numbers and where they can change to appear they are doing something. There will be tight constraints. They can't just kick the bucket over everywhere, lots of people can lose their homes and could go bankrupt. Unless that's the plan of those above them.
There are too many masters to serve as well. Their voterbase is too colorful with different expectations. There will be tasks to be done given by their silent backers. They have to do the bidding of EPP which the Tisza member of. They have to conform to whatever the EU Council says. They have to keep up with Washington's demands. They can't just get rid of China and the existing deals and contracts. And they won't get rid of Russian energy apparently - important to note: it's not just gas and oil, but nuclear too.
On local level in the municipalities the Fidesz holds the majority at many places. Not in Budapest of course, but in the country all over.
And the Fidesz stacked all the offices with their own loyal aparatchiks. They will hamper the machine, but can Tisza get rid of them? Do they have the cadre to fill enough places?
