The article writer has a good summary:
There are three types of campaign you can run during an election: ‘it’s time for a change’ (normally an opposition message, but a governing party can also campaign like this, as Boris Johnson did in 2019); ‘give us time to finish the job’ (the standard incumbent’s message); or (the last resort option) ‘you might not like us, but at least we’re not as bad as the other lot’.
All this albatross can tell is, if he’s saying that, there’s an election a coming.
I remember when I used to have a dentist. Was that at square 1?
