Hungary, which used to be a pretty stable and all around OK country showed it takes one single political misstep to cause a landslide victory in the next election cycle - meaning supermajority. Then that party took the advantage to re-write the consitution to gerrymander and keep the power for many years a-coming.
I think most political parties would do the same, regardless of country.
So next time you curse a politician out at the other end of the political spectrum, also thank them, for actually existing. Nothing destroys a country faster than a (quasi) single-party system.
I always find it funny when people complain about 'Hungarian gerrymandering', as it tells me they know nothing about the place and just repeat what liberal rags screech about Hungary. The election reforms made elections simpler and actually reduced the inequalities between electoral districts.
Its also even more funny considering that the Hungarian election system is objectively better than the one in the USA, in that it is more representative.
