Let’s see. You are marooned on a Greek island and I’m in England. There are a lot of the great unwashed and old who still like Johnson but the middle classes and younger people don’t. The Tories I know are aghast at his antics. He is loathed in Scotland and most of Wales. Business people are fed up with the whole charade and want to Remain in the EU.
Assume that he is still PM at the next election, if he has a got a deal with the EU or still pretends that he wants one he’ll split the Leaver vote between the Tories and the Brexit Party and lose. If he comes out for No Deal then most commonsense people everywhere will vote for the opposition parties. He’ll lose Scotland to the SNP, Tory seats to the Lib Dems and the DUP will lose out in Northern Ireland. He might pick up some Labour seats in the North. The most likely outcome of which would be another hung Parliament. Back to square one. Then another Referendum, won by Remain.
However, I think the accident prone Johnson will be finished in the next few weeks. He’s going to be buried under a mountain of disobliging leaks and revelations from the new army of enemies he has created.
