Bojo always looks like he just rolled out of bed
It’s a known fact that he does this on purpose. He’s been reported to mess up his hair like that before interviews and public appearances because he disarms his opponents by seeming like a harmless buffoon. It’s important to remember, he’s not just an incompetent dumbass who’s fucking up every step of the way like some racist Mr Magoo.
He knows what he’s doing. He’s not some super genius but he has the good sense to lower your expectations from him to hide how much of a threat he really is.
It’s also a (sadly very successful) ploy to seem relatable to the lower middle and working class, the way he dresses like a bum and acts “colourful”, all his histrionics, etc…. because it distracts from the fact that he is and always has been, a very wealthy man, bathed in privilege, who attended Eton and then Oxford, wrote for the Times and the Daily Telegraph, etc. etc. Could you tell all this by looking at him? No. Which is why this shit works.
