The point around his manifesto not being radical is one that resonates strongly with me. I find myself in a position where my personal politics, it appears, is now considered extreme against the backdrop of British politics. Public ownership of essential services and redistribution of wealth were not radical concepts in my youth and I still don't see them as being so. However, it appears there's a general consensus, as witnessed in various "Libcafe" threads, that the Caf is very left wing too.
I feel alienated by a political system that has options of very right, right or a centrist position that has Overton Windowed significantly to the right across my lifetime. I cannot see how, in this environment, a political party that can be elected to Westminster and form a Government can ever be one I can vote for.
I don't know Starmer. I have no strong feelings about him personally. However, his political stance (such as it is) so far and the direction he seems to be taking Labour in order to follow a strategy which is believed will win votes in England is of no interest to me. A party that can attract Tory voters is unlikely to be a party I want to vote for. I want a well led party guided by principle and what they believe in, not pandering to Daily Mail and UKIP warped optics. I don't want the Democrats or the Republicans but with colours reversed. There need to be choices across the political spectrum and a voting system that can reflect that.
It is, as an aside, for these reasons that Labour lost Scotland decades ago where the politics, dominated as they are by the population density in the Central belt, are centre left. Or extreme left as it seems such views are now seen.
