re. Your comment that the bar was set unnaturally high (i.e. needing the support of 100 MPs) - it had to be a high bar in the circumstances.
If the bar was set at 50 MPs, we might have ended up with a leader (likely Johnson) who did not have the support of the parliamentary party.
That would likely have seen, in fairly short order, another forced resignation, and yet another leadership contest.
Johnson being able to charm a section of the public is all well and good, but he also needs to be able to command the confidence of the government and his own back benchers. He had that confidence once, but not anymore.
