-- The Democrats are never going to win on racial issues alone because minorities are still a minority of the electorate.
-- The Democrats' base is the working class, and the vast majority of that is working class whites. That has never changed, nor should it ever change, given the positions of the parties.
-- Trump has made a strong red meat appeal to working class whites on immigration and trade. He positions himself as making a business proposition (which he certainly understands): their vote in exchange for promising to look out for their 'interests'.
-- The Democrats have traditionally made this exact same kind of appeal on economic issues, but are letting themselves get outflanked.
-- There are a lot of people out there who aren't thrilled about Trump, but all they're hearing from the Democrats is, "shame on you for being a racist". Human nature suggests this doesn't work.
1. Of course not. Where did you get there idea that Democrats are a minority issues party?
2. Yes, their base is working class and middle class, though working class whites have essentially left the party in droves since 1980 and more recently 2000.
3. The usual suspects in the working class white demographic would probably vote Republican anyway, even without a specific appeal.
4. The Democratic Party is a fundamentally different party from the 1960's-1980's.
5. So, you have a focus group you've been studying or is all of this just a feeling?
