Tory San Francisco, Boston, Portland and Seattle
Don't forget about Tory Denver and DC
Tbh this is an effect of me using household income to try and estimate the fact that Labour tends to win in higher deprivation level/poorer constituencies. Which in a US context ends up meaning that much of the normally Titanium R rural South ends up as Labour (since it is a poor area of the US after all!), while most US big cities (which aren't necessarily wealthy, but do have high incomes because of the high CoL)
Indeed, if I use such a similar methodology for the UK, I'd end up with lots of wealthy constituencies in London that are held by Labour and that by my methodology should be "Tory" because they have high incomes.
Some of these constituencies that ""should"" be Tory based on income but are held by Labour include Battersea, Putney, Westminster North or Hampstead & Kilburn; the latter 2 of which weren't even marginal seats in 2019
On a similar but reversed situation, a bunch of poor Tory constituencies that my methodology would have assigned to Labour would include Blackpool South, Great Yarmouth, Walsall North or Stoke-on-Trent Central; again with 2 constituencies here not even being competitive.
Something to note is that Labour win very few rural constituencies, poor or not, and those that they do/did generally had mining or heavy industry. But in general, there is nowhere near as much rural poverty in the UK as the US.
(Side note: Alabama is also very disturbing to me. The northernmost seat (the 5th district) would probably be the most Labour after the VRA 7th district, due to its TVA and union heritage.)
