She was so desperate to be PM she didn't fully think through the ramifications.
I honestly don't think you can say this, unless you know the woman personally, and she's actually admitted this to you.
We all knew the ramifications, and if we were in any way unsure, they were driven home clearly in the immediate aftermath.
Cameron scarpering, and the look of sheer horror on Boris's face when the realisation of the result dawned on him. I've never seen someone look so traumatised and ashen.
Remain was supposed to win by a small margin, and he was supposed to swoop in, and say, 'there's enough of a climate for change, you don't have a mandate anymore Cameron, I'm taking over' - he never in a million years actually thought he, or anyone, would have to negotiate and lead Brexit.
That's why they never bothered their arses to come up with a plan.
May knew exactly what the lay of the land was, IMO. How could she not?
