Yes, it's from ConservativeHome, and quite long, but it is very informative. It is really interesting to see how the key party political players in the NO to AV campaign were Labour - in particular ex-MPs Jane Kennedy and Joan Ryan.
And it is fascinating that for all the talk of a "progressive majority", the NO campaign had Labour and Tory sources working, phonebanking and strategising side-by-side, whereas the YES luvvies only met twice a week.
