The people who support Farage wouldn’t care if he fucked a pig live on national television. They don’t like him in spite of his grifting and shady deals. They like him BECAUSE of his grifting and shady deals. They see him as getting one over on the ‘elites’ and don’t recognise that he’s one of them, because they saw a photo of him supping a pint of short date ale in Wetherspoons and spouting random shit about immigration. He has created an outgroup for the people who were the outgroup, and that has made him something of a Svengali to them.
