Watching it all from afar, I have a feeling that people are looking for something different in politics, something less centrist and 'safe'. In fact, the post Thatcher/Reagan world has not been kind to many ordinary people. Safe for business perhaps, but.......
These days world seems to be run by corporations and mega businesses, and privatised systems that used to be in public hands, with politicians doing what the mega powerful tell them to do. People are starting to get resentful.
Where I live in Queensland Australia they elected a Tory State government with a massive majority about 3 years ago. They went power mad, especially as this state does not have an upper house, and the Labour opposition was reduced to a mere rump. It was impossible for Labour to get back - the numbers were appalling. I said they would, but I was laughed at.
But they did. Just. And they are reversing the right wing damage that was done.
Strange and unpredictable things happen in politics.
We are living in interesting times.
