The facts are overwhelmingly against you, and the more people focus on the reality the worse it is for you and your case. Your best bet in these circumstances is to perform a manoeuvre that a great campaigner describes as "throwing a dead cat on the table, mate".

That is because there is one thing that is absolutely certain about throwing a dead cat on the dining room table – and I don't mean that people will be outraged, alarmed, disgusted. That is true, but irrelevant. The key point... is that everyone will shout "Jeez, mate, there's a dead cat on the table!"; in other words they will be talking about the dead cat, the thing you want them to talk about, and they will not be talking about the issue that has been causing you so much grief
