 The thing that's in doubt because of the vagaries of Britain's voting system is whether the Conservatives are going to suffer a bruising defeat or to be truly decimated. But actually, if you step back from it all, it looks like Britain is going to have a political earthquake, but a rather unusual one in the sense that there's no real kind of profound policy fault lines. I mean, Labour isn't promising some sort of radical change, of course, and neither is an apathetic electorate really expecting one.
