Ok well let me spell it out.
The Tories' core voters are middle class people in their millions and retired people. The middle class are being pinched hard, the retired have lost their faith after Covid, partygate, lies and ppc nepotism scandals. The Tories desperately need to establish they are a stable, sensible choice that appeals to EVERYONE (because MC voters do also care about WC and don't want others to suffer) whilst making choices that will favour the MC as well. They need to be in touch, to repair the damage done. To soothe wounds.
Rishi has a stable marriage and seems sensible but his wealth is very off putting. People think he is an out of touch rich person who only cares about rich people. Rishi keeps validating this by pulling stunts like the one above.
If he wants to win the election, he needs to cap profits for the energy companies and supermarkets. He needs policies that will make everyone believe, if only for the 18 months until the election, that he is in touch and does care. That he understands what it's like to choose between heat or food.
Even with this, the lack of faith is so strong that people are unlikely to believe again in a party that has cheated them and lied to them. The disillusionment is very strong.
