I'm not sure on your last point because if one thing we know is that Johnson just like his mentor Trump will only continue with the corruption and lies. The cost of living crisis like covid was for Trump will be Johnson's cryptonite. Granted they will always will have a base that will support them whether they shot someone in broad daylight. But this cost of living crisis would bring anyone down unless its being handled well. Johnson like Trump doesn't have the competence to deal with it.Imagine the electorate in England will give the Conservatives a caning in the local elections, three weeks tomorrow, yet that same electorate will likely return them in the next General Election.
The Conservatives can’t find an alternative leader, a situation that won’t change, and the electorate in England will likely balk at the political alternative. Fascinating situation.
