It is total rubbish to suggest that this (gathering targeting data) is difficult for a political campaign, let alone impossible. It can be done, start to finish, in less than an hour by someone who knows what they are doing. When I go and give evidence to the DCMS, which sadly will have to await multiple legal actions, I could demo why they were lied to by getting someone to start from scratch on a laptop at the start of the session and shouting ‘finished’ when the DCMS is running its own targeted Facebook ad campaign with zero use of electoral data.
