Already did. The fact that it would be a no-deal or shitty-deal or not-such-a-good-deal-after-all Brexit.
Ok, so what part of the referendum question referred to a deal? Explain the relevance here?

Because the negotiating a deal thing isn't even a requirement. The "leave" camp have largely accepted negotiations for a deal, as a compromise. If we can keep some of the mutual benefits, such as trade and freedom of movement, on the table, that's great. But when we voted, there was nothing about a deal. So the "no deal or shitty deal" is only relevant for leavers if we leave with a shitty deal. That's still better than a no deal for the remainers, so it's the leave camp who are shafted by a "shitty deal".
