It's descending into an amusing farce, with every candidate claiming to be the unifier, but the Conservative Party divided between partisan factions.
It still looks improbable that Boris will win. I think the members of parliament (MPs) will vote for a bureaucratic, competent-seeming type this time. But if Boris makes the final two, he may win, because the party members out in the parliamentary constituencies still like him, even if many MPs do not. It's the same difference of opinion that installed Liz Truss.
My assessment of him is the same. He's far the brightest and most interesting candidate. He's good on the big picture stuff. He has a strong record at elections. But he's not so strong on discipline and details. So you get an imaginative guy who may have the best shot at retaining power but with obvious flaws.
