Livingstones a typical champagne socialist, wants everyone to pay a fortune in tax, but does what he can to avoid it himself, hypocrite.
Something endearing about Boris though, but can't quite think what it is.
He always speaks his mind, calls a spade a spade. In this media driven world, thats interpreted as being "bumbling oaf", but the public see it as being sincere and genuine, rather than these so called "professional politicians" only ever saying what will look good in the papers sounbite stories. So whatever you think of his politics, you end up being drawn to him as a person.
