Bromley & Chislehurst by-election

[Serenity Now]

I'm still a little puzzeled as to how the LibDems came so close here though; does anyone know why? I have to admit not following this by-election at all, until the last few days.

Maybe their drift to the economic right is helping them in places like outer london, which aren't all that socially conservative. They might be of a potential "orange" flavour, but the Lib Dems underperformed in the general election (failing to take places like Orpington and their vote falling in South-West London).
