They clearly thought (and presumably were advised) that this was the best approach. I think generally politicians want to run positive campaigns, but are advised about how successful negative campaigns usually are.

I think they underestimated the degree of animosity towards the EU. They were probably also surprised that so many of their colleagues actively promoted the leave cause.

Given this, I don't think they could have swung it with a positive campaign.
