Demographics show that whites really really really like Trump, and everyone else doesn't. Which mirrors the rhetoric of Trump I (hope) any rational person can agree.
In the case of such polarized racial politics, the Democrats needed a white male to try to not further inflame the white base and pick off as many white voters as possible. That left a nonrepresentative candidate for the almost-majority minority "everyone else".
Racial politics have underpinned presidential elections since... well, slavery. This one was no different, it just had the sad spectacle of overt racism rather than at least SOME window dressing overlaid on the "Southern Strategy" since the civil rights era.
