Was always likely, I believe some were written on the day she was elected and only the suspension of Parliament due to the Queen's death postponed their delivery, she's way out of her depth and relying on a Cabinet of very little experience and few big characters, she's tried to prove she's not a weathervane politician by trying to be decisive, headstrong and define her own brand of leadership, but has ended up being a divisive, headcase that many of her party, especially in Parliament, don't want to lead them.
I suspect many who saw her as the continuity, place holder until Johnson was off the naughty step will see that she's not interested in playing that role and I suspect others will be disappointed at how she has cast aside policies that were integral to the manifesto that gave the Conservative's their GE victory, I think the One Nation Conservatives, in particular, are genuinely concerned of the path she is taking and mutterings of defections will begin to take shape, the fact that so many high profile figures have demurred from serving in her Cabinet is a factor and I think most importantly of all they've seen no bounce, in fact the opposite, in the polls and how wooden and poorly she comes across and realised that she's not going to attract the cult of personality Johnson voters who switched at the last GE.
Theresa May, retained the majority of the big guns in her cabinet and attempted to be a unifying figure, but she ended up been eaten alive by the voracious appetite of this split party, Truss, who has little of May's experience, compromise or political sense of being any shade of grey to suit, will either go the same way or split the Party so fiercely that instead of consuming her it will eat itself.
As others have said it's quite frightening what some will define as democracy to suit their means, how some will flip flop position to suit their own best interest and how others will do nothing but fan the flames on the Bonfire of the Decencies that Truss and co are implicit in igniting.
It's almost like it's a deliberate act of sabotage to create mayhem and short the economy.
