I'd imagine the hardcore Conservatives will see BoJo as the only possible "Stop Corbyn" candidate - Amber Rudd is too high risk and not well known enough, even though she did very well in the campaign.

The problem is that, by all accounts, while BoJo might come across as a nice guy by all accounts he'd likely make an awful PM (e.g. read about the chaos that was his last leadership attempt).

He would be an absolutely shambolic PM.

"Idiots love Johnson’s contrived, clownish TV persona, and so will vote for him even if his policies mean they’ll be living under a flyover and cooking rats over a brazier." - Daily Mash http://www.thedailymash.co.uk/politics/politics-headlines/br...

The only 'chaos' I recall was trusting Gove, was there something else?

"All Out War" by Tim Shipman has a lot of the details of the post Brexit manoeuvring for power - Boris appeared to be completely disorganised and with a poorly managed team. One particular event described is where Boris probably lost the PM role because he got mixed up about sending a text to tell his team to tweet that Andrea Leadsom was joining the Boris & Gove team. Leadsom backed out after hearing nothing from Boris and announced that she was running on her own behalf and then Grove did the same.
