Re At some point the left / not so humungously right of centre need to ask themselves "what are we doing wrong?"
This is really interesting. You could argue the Left have done something wrong, or you could argue that populism dismantled the left.
The old "them and us" dividing line used to be rich versus poor/white collar versus blue collar etc. If you were a blue collar worker you voted left and if you are white-collar you voted right. Then populism came along and began reaching out to the blue-collar workers/the working class/poor and falsely suggesting that it provided these voters with a voice. To achieve this it started to tarnish the left with accusations of elitism being part of a "swamp" and highlighting identity politics as the key dividing line. In reality the majority of left-leaning voters do not wake up every day and think about identity politics as their first thought, they are more concerned with healthcare, fair pay, parental leave the climate, education and so on. That this was a neat way for the populists to turn those voters against the left by creating a division and fuelling arguements only really very leftists were passionate about to sow discord.
Let's say you have Elizabeth, a 18-year-old black woman who lives in a council flat in Tower Hamlets and you also have Joe, a white working-class 18-year-old man from Bolton. In reality Elizabeth and Joe probably share a lot of experiences and understandings but populism has convinced Joe that he has more in common with Jacob Rees-Mogg than he does with Elizabeth, and populism has ignored Elizabeth entirely, (often questioning her legitimacy as a UK citizen) and has crafted the perception that all the left are elite.
So has the left done anything wrong or have they simply been slow to realise the dark tactics of populism?
Also, one could argue that the Democrats have got it right given their candidate now has the highest number of votes to any presidential candidate in history.
I once despairingly thought no-one could ever beat Trump. But now we know, Biden can!
