This Good cop bad cop game doesn't work that way brehThe problem is very simple: Democrats focus on various "identity" issues, and large segments of people from each minority group in their coalition feel like the Dems prioritize the interests over other groups over their own.
This is the problem trying to hold together a coalition that consists of so many different groups with different interests.
The obvious solution is to focus on issues that appeal simultaneously to most/all groups: economic issues. But the Dems don't want to do that.
