It's a trite and attractive bon mot, but I don't think it's more true of Johnson than of most politicians. Being popular is part and parcel of being a successful politician, along with saying what people want to hear. From people I know who worked directly for him when he was London Mayor, the clear message was not to be fooled by the amiable HIGNFY buffoon act, he's a scarily intelligent operator who isn't afraid to make decisions.In the immortal words, he waits to see which way the crowd is going and runs to the front and says "follow me".
He will. But if you think he's playing then you've been suckered.Let him play PM for a while and then just f*ck off.
