Oh yes, but the left made more ground than anyone else. GroenLinken gained 400%, D66 gained 7 seats, Christian Democratic Union (which isn't right-wing per American Standard) was up 6. The only losses were from the coalition, mostly due to the fact that the leader of the Labour Party focused on EU issues as opposed to domestic issues and pissed a bunch of people off as a result. Even my liberal ass wouldn't have voted for him.
The only people that need to "open their eyes" are the people that think this is a ground-breaking gain for the PVV. This isn't even the best result the PVV had. Back in 2010 they lead opposition with 24 seats, netting a gain of 15 seats.
