And if they do win that by-election, what stance will they take on the NHS? Or education? Or transport? Or any local issues? Who knows, but the voters sure as hell don't, because the Brexit Party manifesto consists of "magically make a really good Brexit happen by some means we haven't told you yet" and that's it.
I'm happy to call anyone voting in those circumstances ignorant, in the dictionary definition of the word. You vote somebody in blind like that, you deserve everything that you get. You want to fix this country? You start by sorting out the political ignorance of a large swathe of it. Then maybe we will elect a better class of politician, rather than the chancers, liars and con-men infesting the political scene at the moment.
