Who would be the best Democrat for each of these voting blocs?

[Crumpets]

The last two Democratic primaries have revolved around four main voting blocs, two of which are needed to be a strong primary candidate. Going forward to 2020 and looking at the main speculated candidates, where would they draw their strength from? Who would do very well with one bloc in particular, and who would be able to pull multiple blocs together to make a winning coalition?

1. The Obama -> Sanders bloc - Liberals, progressives, millennials

2. The Obama -> Clinton bloc - Urban centers, African Americans

3. The Clinton -> Clinton bloc - Women, Latinos, what remains of Southern white Democrats

4. The Clinton -> Sanders bloc - Disaffected Democrats, rural whites, working-class Midwesterners

Here's a map for added context:

[Hindsight was 2020]

1: The Obama -> Sanders bloc Elizabeth Warren
2: The Obama -> Clinton bloc Cory Booker
3: The Clinton -> Clinton bloc Julian Castro
4: The Clinton -> Sanders bloc Sherrod Brown
Now who would put together the best coalition? Probably Booker or Castro, Brown seems to lack an "it" factor to be the top of the ticket and Warren I think is viewed too much as an elitist college professor type that Trump would get a lot of red meat from. While Booker is very charismatic with a put up or shut up background between saving someone's life and going on food stamps and Castro like Obama had a poor upbringing that the media would eat up an can run on being a successful blue mayor of a big city in a red state
