2016 Referendum and Johnsons popularity at the 2019 GE suggest there is probably enough Clarkson-esque bigotry out there to make it a worthwhile venture to blur pricinples away from the Corbyn yardstick. To be fair to the guy, he's been lambasted (by said bigots) for saying on air he'll be undertaking unconscious bias training, on the back of "that" BLM comment.
He’s not going to out-racist the Tory party, is he? If that’s what people want they already have a home. The latter comment just sums up the obvious flaw in the strategy - he’s made a commitment that tries to please everyone, and all he’s achieved is winding up the bigots by acknowledging racism exists and antagonising much of the left for performative nonsense.
