This'll get the under 40s voting for them. "You know those other Tory Prime Ministers you can remember? They were all shit. You know who isn't? The current one. Yeah, that guy you really don't like. He's great. Sorry we told you others were all good when they were up for election.."
Seems like "this stuff worked for Cameron, let's try it again". Even Nick Macpherson, the very austere former Permanent Secretary at the Treasury, has said they should have borrowed more at low interest rates in that era.
(btw, why is there no controversy about Macpherson massively endorsing Tory policy after his retirement? Seem to have missed all the “right wing civil service” stuff)
