Well, let's talk some sense.

In fact Boris has done absolutely nothing of any value as mayor of London (save implement some previous Labour plans) and has failed to show any grasp of policies or appreciation of the lack of viability of his glib assurances. For reasons that I do not understand people regard Ken as a megalomaniac but his policies have always been better for the bulk of Londoners. This election in London was not decided on policies but on some sort of foolish personality cult.

More dangerously, the mayoral election was however probably decided by badly biassed press coverage, the London evening papers (and City AM) being in effect part of Boris propaganda machine - or as Boris's educated and nuanced expression would have it "fucking bollocks".
