Yes, that's interesting: I think Khan could have been beatable but the Tories chose a dribbling halfwit who I wouldn't trust to run a school raffle. Why didn't they pick a credible candidate?On balance, however meh Khan has been, I'd be massively surprised if London elects an oddball like Hall with limited experienced.
Tories could have chosen from a number of MPs who would have given Khan a race. They didn't.
