There's an interesting article
here, which makes the argument that he had a Trumpian mandate to smash the existing 'blob' (what Americans call 'the swamp') and remake the British government in a way which took advantage of Brexit and delivered benefits to the country. He had a couple of good policy wins - supporting the Ukraine and the Covid response (which was as liberal as public opinion would allow) - but otherwise the impression was of a policy-free zone: silent on the subject of woke, increasing taxes, and business-as-usual drift on reforming the state bureaucracy. In other words, he was captured by the blob that his electorate wanted destroyed.
The ban on selling ivory (there is already a ban on its importation, so we are talking about antiques) and proposal to ban trophy imports were classic symptoms of displacement activity, of interest to only a minority, but the pandering to that minority is an obvious rejection of 'live and let live' conservative values. With luck, this nonsense will be dropped.
He was also the victim of bad luck and incompetence in others; his media operation was useless, allowing his political enemies to dominate the news agenda (in particular the opponents of Brexit), and his whipping operation - the management of his own party - was also disastrous. In rapid succession, the country has been enlivened by (male) MPs from Boris' party: (1)
watching porn on their telephone in the House of Commons during a debate; (2)
getting drunk and fondling other men; and (3)
crashing a car and running away whilst dressed in a black leather mini-skirt, high heels, and pearls. How on Earth are such obviously unsuitable people chosen to stand for election in the first place?!
His likely successors are an uninspiring bunch, none of them with Boris' charisma, and the leading candidates acting unpleasantly disloyally towards him. The best solution would be for President Trump and Prime Minister Johnson to swop places.
