Interesting if he does. I suspect he will appeal to a lot of metropolitan Tories, particularly as the offical candidate is so unimpressive, but also attract some Labour voters who see Sadiq Khan as having been pretty ineffectual, and the Lib Dems, who approve of anyone that owns more than one pair of walking boots. Probably not enough to win outright, but if he then picks up the second choice votes he could give Khan a run for his money.
