Not sure that is the case, tbh.
Everyone goes on and on about "how much people like Boris", but there is really almost no evidence to suggest he is competent at anything - running a government, running a general election campaign, being Mayor of London, journalism, writing history, presenting HIGNFY or basically anything else. He had a free run at the Tory leadership and only won that against a load of nonentities by disappearing whilst leaving his backers in every major paper to chat nonsense everywhere on his behalf (and don't forget there is the actual tape of what his and Carrie Symonds row was about that is still to come out).
Now I have no doubt that in a GE the likes of Allison Pearson, Toby Young, Dan Hodges and the rest will be all over the place talking the same rubbish, the media will be full of the same fibs that it was last time, and the people who pay will stump up yet more fortunes to support the party. I also have no doubt that during the campaign he will say or do something that makes it abundantly clear what he is, some immense calamity that will render all the puff-pieces meaningless.
I mean, he is the first Prime Minister - ever - to lose their first vote and his response to it (kicking out some extremely long serving Tory MPs) will almost certainly mean he loses his next vote as well, and probably loads of the ones after that too. He has managed to in six weeks get Corbyn, Swinson, the SNP and Plaid from a position where they mutually loathe each other to the point where (as they did after the vote today) they repeat each others demands.
If he makes the election No Deal Brexit vs the rest, he will make it almost impossible for the opposition to not collaborate to oppose it.
