keir Starmer was the leader of the labour party, they tend to be public sector or civil servants like teachers and lawyers. Conservative party tend to be business orientated like bank employees and business directors. There is some lee way between the two groups but they're both a fish out of water when running a county because it is a different landscape to navigate.
Andy Burnham was the Mayor of Manchester so his role was similar to running a country. Running a city and running a country are similar I think, just on a different scale. Perhaps he will have better luck.
I feel like we have been trying different things now, like we're navigating a labyrinth in the dark and every time we reach a dead end, the leader steps down. It has been like that for about 10 years. Will we find the exit to stagnation? I don't know.
