I often think of a former colleague of mine at PF: late 30s, recently married, left us for a high earning job in the private sector, mortgage, lives in leafy SW Lon. Privately educated, my guess is her kids would be too ideally. Husband and she met at Cam. Used to be rock solid Tory. Now votes Lab.
I wonder if she has noticed how few of the Tories she (we) knew at university are even voting for the party now.
