Two thirds? You got a link to any of these polls? I'm not disputing it but from my own experience and the Leavers I know, very few want us out without a deal. Most do want the Brexit impasse resolved and soon though, just like most Remainers, and two thirds of Leavers saying they'd leave with no deal doesn't necessarily mean that's their most preferred option, and is probably as much an indication of the nation being pissed off with the whole thing as opposed to actually wanting No Deal. Just like those Remainers saying they'd take a soft Brexit but it isn't their preferred option. Christ, I know one staunch Remainer who wants us out - preferably with a deal of course, but if it comes down to No Deal then so be it in his eyes. It's not what he wants of course but he's probably more receptive to No Deal than I am!
I guess what I'm trying to say is that the lines have become so blurred that it's not as simple as Remain/Leave/Deal/No Deal anymore, and there are overlaps all over the place.
