The Tories are mostly bonkers so they'll elect Boris. However it'll become clear from day 1, what a mistake they've made, particularly for anyone who wants delivery of Brexit. He'll be another Theresa May within weeks, the same people now part to of his cult, will be despising him within weeks. The bonkers people will then go back to Farage, whilst the Tories lose power.
See? There's always a happy ending
