You're not going to get what you want unless something massively unexpected happens (Last YouGov poll I can find has Wales voting 45% Labour and just 18% Conservative).
More importantly, and I can't stress this enough, what happens in this election will have absolutely no bearing on 'Welsh Labour' as this is an election for the UK government, not the Senedd.
If people want to vote for someone else in a Welsh government election (and they'll have their chance in 2026) because they're disappointed with how Labour have run Wales, then I understand that. Someone voting for the Conservatives despite the utter failures they have been in recent years because they don't like Welsh Labour would be ignoring reality.
Well 2026, is a bit long to wait, to show peoples feeling of how we feel!
And honestly, I would take those YouGov polls with a pinch of salt, they mean nothing.
I would be shocked if Labour get 25% of the votes.
