It already has, starting some 3 years ago 
Last year its spread produced a change of government, from our previous left-leaning and reasonably enlightened group to a right-leaning, ‘centrist’ party that - unfortunately - only gained power by forming a coalition with a small, ideologically driven right-wing cabal on one hand, and an equally small, highly populist party on the other.
I was ok with this at first. From a social psychologist’s perspective I partly view democracy as a form of self-correcting ‘game’ that satisfies (most of) its population by allowing its main voting blocs to take turns at the wheel. A lurch leftward is corrected by a lurch rightward and so on and on we go. None end up completely satisfied, but neither do any end up completely dis-satisfied, and therein lies democracy’s strength and - ultimately - stability.
(However, when there’s a large non-voting bloc, which happens here as it does in your country, that’s cause for concern. Democracy can’t work optimally IMO).
However, it turns out the populist party was filled with lobbyists, many of whom achieved positions of power as part of the coalition deal. For example, ground-breaking legislation to limit tobacco use and supported by all parties in the previous government was promptly reversed by an ‘associate’ minister on account of the ‘damage’ it would cause to tobacco companies profits: the huge costs to our mostly taxpayer-funded health system and population health be damned!
That’s just one of many bewildering decisions.
This is nothing like as bad as what it seems lies in your near future…but it’s more than troubling and - I think - underscores the questions we already face for democracies world-wide.
