Based on the observation that Remain Conservatives seem willing to do literally anything except let Corbyn be PM--which makes zero sense because he would be temporary in any case--it seems to me that if there is an election and the choices are Labour/Corbyn or Conservative/Johnson (or LibDem/useless-person-why-don't-they-get-how-third-parties-screw-things-up) then Johnson would win, probably with an actual majority.

If things seem bad now, imagine five years of Johnson running a party with a majority in Parliament.
