The Democrats shouldn’t be distracted by identity politics. They should instead be focused exclusively on the politics of the working class in the white rural areas of PA, MI, and WI and cater to their needs only. That is the answer.
Considering that they are the swing states, their needs matter much more than what the Upper East Side or Orange County thinks.
Democrats are gonna win, let's say PA, by running up the score in SEPA (dreaded suburbanites). They ain't winning rural whites ever again.
That strategy failed badly.
"For every blue-collar Democrat we lose in western Pennsylvania, we will pick up two moderate Republicans in the suburbs in Philadelphia, and you can repeat that in Ohio and Illinois and Wisconsin." - Chuck Schumer in 2016
