I don't think right wing and left wing is any longer the defining factor in politics. It's no longer primarily about economics. For a while now, there also been an authoritarian/liberal (I know, difficult term, means different things to different people) axis to it. Now the fracture, in the UK, the US, France, Italy, Germany, even Tunisia is along cultural fault lines. I mean, hard brexiteers from the conservative side are now mostly indistinguishable from Brexit Party voters and Brexit voting Labour supporters. And centrist Tories and labour voters have more in common with the Lib Dems and Greens that they do with they (former) parties. Both traditional right and left have been shrunken down to the most extreme form of themselves (Corbyn et al are just as responsible for the current mess as the Tories). The political landscape is reforming itself, it's exactly like an earthquake. The tectonic stresses build up and up until the crust breaks, and then settles in a different configuration.
That's what we're in the middle of. The next general election is going to be fascinating.
