There can be little doubt that Davis' stance has drawn massive public support from a nation utterly sick of the apparatus of Statist authoritarian control all around us. There is no doubt that he has acted from the highest principles. It also seems likely he has blown his place on the front bench.
Principles are as rare as hen's teeth in modern politics; Davis' stance would not have been remarkable a hundred years ago, and the pages of Tacitus are sprinkled with Roman senators who put death before dishonour, but the notion that a man will act not out of self-interest but out of an altruistic determination to expose this great wrong is clearly an alien one to our political class.
It is no surprise this morning therefore that comment on Davis' resignation is divided, with blogs and the comment sections of the online media overwhelmingly in support but the editorials and opinions of the political class echoing Robinson's 'bonkers' comment. The political class only seem prepared to accept an MP with convictions if they are criminal ones.
I think the truth is that David Davis has opened a fissure in our petrified political process, and they're not sure how to deal with it on either side of the Commons. We'll have to see how this plays out, but Davis may just prove to be the grain of sand around which will grow a pearl of inestimable price.
