Essentially Germans showing that they are lost and all the media brain-washing has driven them so insane, all they want is to live in a fantasy world of the last century and rot away there.
People advocating for cutting down investments after 16 years of no investments and infrastructure literally breaking down around them (plus things where they are already at least a decade behind the modern world) get votes.
People advocating that mass deportation of illegal immigrants will solve everything (in reality there are basically no illegal immigrants and the total amount that can be legally deported is less than 20k in a country of 84 million) get votes.
People advocating for cutting back imaginary "gifts" for low-income citizens when that raise in social support is actually mandated just as an inflationary adjustment and courts have ruled again and again that reduction far beyond a subsistence minimum is unconstitutional get votes.
People advocating for less climate protection to kill the planet more efficiently (also unconstitutional btw...) get votes.
The government that by any objective metric has already realized more of their promises in 2 years than their predecessors managed in 8 while seeing one global crisis after another and an opposition that has degenerated to pure obstructionism is somehow "the worst government Germany ever had and really should just give up and make space for re-elections".
