It's about the timing. If they ousted him now he'd be able to spin it that the opposition were trying to stop him fulfilling the will of the people.If Boris is so terrible and hated then why doesn't the opposition vote for an election?
They'd win easily surely...?
If we are still in on 1st of November, Farage will tear him apart. Tory vote plummets as does Bojo's personal rating.
Then the opposition can pounce.
