You have to ask, if May is willing to fuck herself over this much - by refusing to hold a vote in the Commons, because she'll lose and then the shit will hit the fan - why doesn't she just not fucking do Brexit? Well,
She takes a position and then she sticks to it, seeing it as a matter of principle that she delivers on what she has committed to. This doesn’t mean that she is a conviction politician. Often she arrives at a position reluctantly after much agonising – as home secretary she became notorious for being painfully slow to decide on matters over which she had personal authority. Many of the positions she adopts are ones she has inherited, seeing no option but to make good on other people’s promises.
