Boris
Almost everyone I read, most of my friends, and my fiancée, appear to see Boris Johnson as something akin to the antichrist. Me, I'm with Nosemonkey.
Someone else (I've lost the link*) said that Choosing between Ken Livingstone and Boris Johnson is a bit like choosing between shit and shite,
which admirably sums up how I felt. Rather Paddick than either, certainly, but that was never a real prospect, and personally I thought, and continue to think, that the shite is just marginally preferable to the shit. The heavens have not collapsed in on us, nor has the Thames risen in protest, and I rather suspect that they won't.
*ETA: via Purplecthulhu I see it was DoctorVee, who now has a followup post.
