There is a certain subsection of Conservative membership that genuinely do strongly dislike maternity rights & minimum wage so I can see why she's saying what she's saying. There are votes in it for her. But they aren't centre right votes.
The problem is that they have to pitch to a tiny section of the public whose views/values are not necessarily replicated in the wider voting public.
Then they become leader and real life/economics gets in the way of implementing the stuff they have promised to the membership who then get arsey.
They also have to contend with their own media who - like the membership - hold more extreme views (or cling to them for clickbait) and so there we see years of Op Eds from the likes of Murray/Frost/Hannan criticising their failure to implement what the membership want and suggesting treachery at the top of the party.
The leader fails. And round they go again.
They can't out Reform Farage. He will say anything, promise anything. And the voters that have switched are not necessarily coming back - YouGuv polling suggested that a large swathe of them would rather not vote at all than vote Conservative ever again. But rather than facing this and making arguments for centrist policies they have to focus on the membership interests.
