Why do Londoners keep re-electing this fool?
Many people you have difficulty to turn out for electing their MP let alone a mayor.
Obviously he election/re-election campaign was slick and promised much probably more social and welfare programs plus pandering to the Muslims and other ethnic groups. Add all that together and probably answered why he was re-elected.
Speak to the average man in the street and they think he is cuckoo but then only the Londoner's who vote elect him.
Like large cities in the US, London is populated by non-natives to a huge majority. Way over 60%, but I don’t remember the exact figure.
