Do a significant number of students actually change their voting address? My experience of university (albeit a few years ago) was that most students who cared about politics would go back "home" for a long weekend to enable voting on the Thursday prior to the long weekend. I don't know why they couldn't just do a postal vote...
When I was a student I voted in my university seat, travelling there during the Easter holidays specifically to vote.
And while the outcome in that seat was not what I wanted, it was at least a close contest, and I felt that my real "home" by then was my university town anyway. I felt that my vote could have made that difference.
The family address was in the sort of seat which has probably been Tory since 1832 so a vote there would have been utterly wasted.
I have a friend who both lives in the constituency and voted in the by election. The Tories made their usual points about clean air zones but were quick to criticize the labor London assembly implementation of the ultra low emissions zone and all its flaws and faults for stop the labor candidate haven't got anything whatsoever of use or value to say when challenged about it and didn't even stand up in defence
This according to my friend was really all that the majority of voters needed to know. If they can't actually put up a fight against one of their parties flagship policies within greater London then why bother was my friend's opinion
I also think this is a highly useful for taste of things to come. Not sure if there will be any further London Westminster by elections between now and the mayoral election but a couple more defeats like that will pretty much set the scene on what's going to happen at city hall next year.
Do the majority of Londoners live in the outer suburbs, though, or do more live in the inner areas?
I can see there being a Tory swing in already-conservative outer areas such as Barnet, Chingford, Romford, Bexley, Bromley, Orpington, South Croydon and the like - but I suspect in the more liberal inner areas, enough people dislike the rhetoric of the likes of Braverman that they are unlikely to bring themselves to vote for a Tory mayor. I can't see areas such as Putney and Wandsworth, which have swung leftwards recently, for example, voting Tory in the mayoral election.
I do hope Susan Hall has more to her manifesto than just scrapping the ULEZ expansion and more police, what's her policy on TfL and getting more funding for example?
It wouldn't surprise me to see a programme of service cuts and fare increases if a Tory Mayor comes in.
But as I said, the dislike of the Tories in the inner, and even middle, boroughs means that I suspect the Tory won't get in.
Uxbridge, Romford, Bexley and the like might dislike Labour and like the Tories, but at the end of the day, they account for only a minority of the population.
