There's more than one reason to celebrate a little in my opinion. Yes, there's some bad news about this election as well but let's see.
One : The biggest party D66 has a preference to go in a cabinet with the biggest left-leaning party which means that there's a possibility for a significant change compared to the current really terrible awful fascist-leaning and unstable cabinet.
Two : The party leader of D66 has spoken out several times against PVV Wilders fascist-leaning party. Several parties also ruled out working together with Wilders.
Three : The party leader of D66 who is likely to become prime minister is openly gay. This would be the first gay prime minister in NL. I consider this a good development for more tolerance (rather than Wilders's hate and division and picking on minority groups).
Four : Now that Wilders/PVV is not again the biggest party it will prevent the Wilders dream of becoming prime minister. In the current cabinet Wilders was not allowed to become prime minister, and it appears Wilders is frustrated about this. Now the initiative is with D66. Wilders can continue to try to distract but is not in the driver's seat.
Just my 2 Euro cents.
