The only reason Youngkin won was because he distanced himself from evil ahole Trump.
I don't think it's that simple.
The Democratic party is often it's own worse enemy. While it's alright to talk about how bad Trump was because he was a piece of shit, and it's alright to talk about cultural issues that need to be addressed, at the end of the day they need more than that. They need real substantive policy issues that they not only need to talk about, but more importantly also fight like hell to bring about, and they just don't do that. They can't just take the easy way out and do just the Trump bad and culture war spiel and call it a day.
They need to do things to very fundamentally make everyday peoples lives better, and they either only pay lip service to that, or when the slightest Republican opposition challenges that they will fold like a piece of paper. Too many of them are corporate shills that are just less honest about being corporate shills than the Republicans.
I also have a feeling at the end of the day the Democrats will somehow warp stuff like this to make it seem like it's the progressives fault, instead of it being the fault of their lack of fighting for things that will actually help people.
