BSE has a problem.
Its campaign has been resolutely negative on every front.
Effectively, the EU is shit, but leaving is shitter.
This might be an effective message to stop people voting to leave, however its going to be at least as effective in stopping people voting at all.
Its still two months away, but the only people talking about it in my world are the political fanatics, and even then, they are primarily the leavers from both ends of the spectrum, maybe 5 to 1.
The odds are still strongly favouring remain, but unless things pick up after the locals, BSEs in trouble.
