You think the EU would have gone ah look at her trying to be inclusive with a plan that at most could get her 5 more votes, let's give her a great brexit deal and forget our wider and longer term interests in punishing all who question us?
She is bound by her own arbitrary red lines, who knows what could or couldn't have been achieved without them. We'll probably never know.
I don't know, I think our Parliament is a shambolic and undemocratic shit hole but if you are going to have this sort of Parliamentary democracy some attempt to recognise it would have been better.
