Promised something beefy. Let's start and see where it goes.

Summary of the election in numbers - minor changes are expected, perhaps when I post this, the numbers will be incorrect already, but still close enough.
Extraordinary turnout, clocked 79,55%.
For now it seems Tisza gains 136, the Fidesz 57, and the Mi Hazánk 6 seats in the Parliament.
Really interesting how these mandates are distributed. From party lists they got 44 - 43 - 6, but the major difference comes from the constituencies, where they elect candidates on the basis of simple plurality. So the candidate with the highest amount of votes wins. And the Tisza could reap 92 seats from all over the country.
The election system the Fidesz created heavily favors the winner. A very slim win can result in a stable majority, and a confident win in a supermajority (2/3). In previous elections this favored the Fidesz, on Sunday it caused them to lose bigly. But shouldn't overestimate the Tisza's overwhelming majority in seats, they got support from the 52% and change of the voters. Some celebrate how all the Hungarians finally woke up, this is a bit of a stretch, that 2.3 million Fidesz voter would had been enough in the circumstances of previous elections, so we can't ignore them.
What I wrote here:  >>/55193/ still stands.

One note: in EU countries the winners of elections have hard time forming governments in recent years, and then they create weak coalitions that crack easily. Probably their electoral system can be blamed. So if one considers strong, stable governments a good thing, then the Hungarian one delivers.
