It is still likely to be perceived as being 'jam tomorrow' or worse still "I want your vote so I'll say anything".
I suspect anything labelled a 'Green infrastructure project' will actually be running out of road by 2024, (no pun intended) there are too many 'elitist' backers who are pushing such schemes now and more climbing on the bandwagon, all very much in the idiom of "don't do what I do, do as I say" as they jet off somewhere, and they don't even realise they are doing more harm than good, in their efforts to look concerned.
From the 'White heat of Technology' from the mid 60's, through to the 'Northern Power House' of the 00's politicians of all kinds and persuasions have been gushing about redistribution to the North, equalising the balance between North and South, replacing past industries with new growth, etc.
Sorry it won't wash, it isn't just old men and women changing their voting habits and risking the wrath of their ancestors, many young people in the North especially after the Brexit delay and debacle, just don't trust politicians any more...full stop!
Most of those who voted Tory, for the first time in their life, actually don't really believe Boris will deliver on his promises, beyond Brexit; but if he does deliver on just a fraction, they will vote him in again. Labour is so distanced in thought as well as ideas from its past roots, it doesn't just have a mountain to climb, but has seas to swim and endless valleys to explore. Boris will have to foul up big time and similarly Labour change its ideas, to get anywhere near rebuilding the 'red wall'.
