Common theme amongst even the sentient brexiters that i spoke to was that there was something they disliked about the EU but they hadn't considered how leaving would actually affect it.
I didn't speak to any fishermen (as per the map above, they're rare in these parts) but i spoke to a few who thought the EU was undemocratic and thought we shouldn't be bound by laws passed by an unelected commission. Leaving aside the misunderstanding of the facts, they seemed to think that a customs union or Norway/Switzerland type arrangement would remedy that.
"The implications of the paperwork." really is a cracking phrase.
