The UK, Netherlands, Greece, Hungary, Sweden, France, Italy, Spain all look as though the far right parties will do well in Europe.
It's all very well viewing protest voting as ' great, come the revolution' but at what price? It just might bite us all on the bum.
Whether it turns out to be nothing more than a protest vote or not is immaterial, people will get what they voted for.
As you have pointed out, this discontent isn't confined to Britain but right across Europe so very few of the EU states are happy with the current situation and want something done to change it. Clearly voting for the usual culprits isn't going to change things.
Sometimes, to effect change means going out on a limb and taking a chance. The alternative is to sit on your hands and keep the status quo - which many are very unhappy about.
