Simon Jenkins makes a point today that I have known since the referendum was announced; that the facts will have nothing to do with the vote. It is utterly pointless to swamp the public with 'facts' and even more pointless to harangue them into listening to credible experts.
My tactic is the right one; for every announcement made by a 'pro' figure, throw out a counterfactual. If they say the EU is good for the environment, broadcast that the EU will kill the UK's natural environment. If they claim leaving will cost each UK family £3k, put out that each UK family will be £3k better off by leaving. If they claim the EU enhances UK security, make the point that the EU actually degrades UK security.
As an individual who is not a member of any campaign, and who has no campaign expenditure, you may lack the MSM attention that a known 'pro' figure gets, but are equal on social media to any of the big cannons. It doesn't take any more than a hundred 'outers' repeating the message that leaving will make everyone £3k a year richer to drown out the Treasury claiming the opposite.
The true point is that leaving is a lot less risky than being shackled to a dying EU that will drag its members into the inferno before it dies. People know this in their guts; facts won't change minds.
