Hard to take I admit, but you need to win the middle ground to get into office, much as you would hate to admit, me too, if you win the middle ground you get elected.
When Thatcher ran to power she appealed to left sided voters, with her little shopping bag for £5 and she won. She, spits, realised that there weren't enough Tories to win an election and adapted.
Whether we like it or not, Starmer has to do much the same, such as Blair did with " New Labour" and like him or not he got 3 election victories on the trott, unheard of with the Labour Party throughout history.
Adapt or die, like we have been doing the last 13 years, dying on our feet.
Or you could hug a tree, pray to you're One MP and vote Green...
