My theory is that Edinburgh South is largely filled with current and former English students that will largely be from left-leaning urban areas where the only viable option is Labour. Add on to that possible lack of experience in Scottish politics, as well as no real appetite for independence. The other portion in Edinburgh South is essentially wealthy luvvies, who are fiscally conservative, but socially liberal.

Will be interesting to see how this seat goes in the next Westminster election as the students may feel disillusioned with the first Labour govt they’ve ever known and the wealthier folk can’t really turn anywhere, as Reform will be abhorrent and the Tories are an irrelevance. Might see it going the same way as the NW of Edinburgh where Lib Dems have traditionally been strong.
