Unfortunately, it does show that the "no deal" option doesn't have the majority view. Neither does "no Brexit" overall. And noone can agree on what the other option(s) should be.
This is the problem for the last 3 years has been one that the Leave side has been studiously trying to avoid - If you ask 100 remain voters what relationship they would like with the EU, pretty much all of them will say "same as we have now". It's clear what "remain" means to both remain voters and leave voters.
However if you as 100 Leave voters what the relationship with UK should have with the EU (and let's face it, they are our nearest neighbours, we do need to trade with them and it's the place most of us go on holiday when we go overseas), you'll get 4/5/6 different answers, with no one answer having more than 50% agreement.
This is the problem that Leave needs to address, unfortunately, they seem to think Remain have a duty to do that. Leave couldn't agree amongst themselves what sort of relationship with the EU they wanted after leaving.
Just leaving isn't enough of an answer - until they can speak with one voice about how it will work, they won't win over any remainers, and they do need to get the remainers on side if they want to avoid a campaign to rejoin the EU being successful within the decade.
