This is an interesting Irish Times interview with Richard Dawkins about Brexit. I don't generally agree with him, but I really do on this.
With regards polls, they show that most leavers would prefer a deal. However, if the choice was between remain and no deal, a small majority would prefer no deal.
Not all leavers = no dealers. Some leavers are horrified at the prospect of no deal as it isn't what they thought they would get (and why would they, as the leave literature said that we wouldn't leave without a deal, which would be easy to get).
Trying to prevent no deal does not equal trying to prevent Brexit. If you'd listened to the debate in the HoC on the night that they voted on the Benn Bill, you'd have seen passionate speeches from people like Ken Clarke and Nick Boles who said that they wanted to honour the result of the referendum, but not by leaving with the catastrophic no deal. Anna Soubry said that she simply wants the chosen deal to go back to the public, to sense check the 2016 vote and make sure that people are happy to leave with the proposed deal. These are not unreasonable view points. Why don't people want a chance to say that, yes, we still want to leave and we're happy with the negotiated deal? Why is a confirmation vote so hideous a concept?
It's pretty clear that not every one of the 17.4m voters was voting for the same version of leave. Confirming that they are all still happy to leave, with the deal on the table, is sensible.
The whole reason we are in this mess is because of trying to honour the vote. The problem is that it's really rather complicated to extricate ourselves and there is the potential of harm to our citizens if we go down one of the leaving routes. Our MPs have to act in our best interests, and leaving without a deal really isn't in our best interests at all.
And the only reason BoJo hasn't thrown the DUP under the bloody bus yet is in case he needs their C&S agreement after the next election if he fails to get a majority. Otherwise their opinion on the backstop wouldn't even be holding him back. Because right now, the agreement is worthless.
