None of those are going to hurt the Tory vote because respectively a) they think the government’s doing its best/don’t think the rona is real/think the young and minorities should be sacrificing themselves to keep the whole thing going anyway, b) don’t give a shit and c) No Deal is Good, actually.
For as long as the Tories manage to shelter their coalition from the material effects of their policies, and the opposition are offering “same shit but more efficient”, they’re going to be on 40 points or thereabouts.
