I honestly don't remember much of the debate being on the EU, though that could be my memory or just my experience of it. It's clearly important, I simply don't agree that it obviates the pledge. UKIP were around, and as I pointed out in another comment (and confirmed by a sibling's helpfully finding the polling info) there were (are) plenty of independence supporters who also wanted out of the EU. If we take the low percentage from those polls of 25% then that eats that 45% by around 500k. I'm not saying that's how it would be this time but it doesn't make for a strong case.
