nope it was from
this:
" it is possible to identify the constituencies which have had the most significant change of heart over the past six years. Of the top 20, all but two are Labour seats. Barking in East London for example voted to Leave in 2016 by 60% to 40%; but now 54% of voters in that constituency think Brexit was a mistake. West Ham, Birmingham Ladywood, Dagenham and Rainham, Middlesborough, Walsall — all of these fit a similar profile: poorer areas with a very high proportion of ethnic minority voters. Many of them supported Brexit at the time, and they are now the most disillusioned of all with the project."
so in my crappy shorthand that richer areas being least disillusioned => they're happier about brexit
