I never really worked out what was going on between Gove and Johnson when May was chosen as Tory leader. Either the two of them hate each other's guts or it was all a sort of double bluff.
Gove and his wife might think he stands a chance, but he's toxic. He contradicts himself every time he opens his mouth and Labour would crucify him. Even Cameron sacked him because he was so unpopular.
The 1922 Committee (the men in suits) is apparently already putting pressure on Johnson. Whatever they do, they'll want to win the next election. Sunak is flavour of the month, but that's partly because he's an unknown. I don't know how much depth he really has.
I agree with janeainsworth that Hunt seems to be growing in stature, not that it's very difficult with the competition. He's a Tory, but at least the kind of Tory with whom you know where you stand. He's also a Remainer, which probably isn't very popular with the current parliamentary Tory party.
Whatever happens over the next year or more, we're all in for a bumpy ride and I'm afraid I can't see an end in sight. The UK is going to end up much diminished and probably without Scotland and maybe a flare up of trouble in Ireland. Apparently, even the Brexiters are complaining that the new passport is the wrong kind of blue! And the FT is reporting that the Tories are about to break the election pledge on the pension triple lock.
