'Should Donald Trump be prevented from making a State Visit to the United Kingdom?' This is a Petition on the UK Government Website and it has attracted more than a million supporters.
But the word petition already leaves a sour taste in the mouth. It tastes too much like asking someone superior and powerful to grant a favor. Much better to give it the legal form of a binding referendum, that way no energy is wasted in signing up and disappointment is prevented. The last thing the reigning Politocracy wants is to be told what to do by the citizens.
